The Weather and Meteorology thread


23 Sept Wed to 29 Sept Tue 2020.

Guys, get ready to celebrate the arrival of the First Western Disturbance, more popularly called WDs, arrival towards the end of Sept, about 28 Sept 2020 approx.

This also means the start of the snowfall season brought by WDs to the Northern most parts, and gradually, in coming months, bring snowfall to the entire Himalayas.

Keep a check on this WD, and by tomorrow we will see what all areas it will affect.

Let me hazard a guess, if this the start, the Passes may just close earlier this year. And with Rohtang Tunnel being inaugurated just in time is just great.

Travellers get ready. Exiting times ahead,



Retreating monsoon rains worry paddy farmers in Maha
October 08, 2020 09:41


Farmers in Maharashtra's Gondia and Bhandara districts who have grown early maturing varieties of paddy are worried as the retreating monsoon rains pose a threat to their standing crops. Agriculture officials in the two districts told PTI that irregular drizzle will not affect the crops, but if rains continue, then it will cause damage to the standing crops.

Gondia and Bhandara fall under the paddy cultivation belt of the state and nearly 60 per cent farmers there prefer growing early maturing paddy varieties, which are ready for harvest in 90 to 120 days, officials said on Wednesday. Farmers have cultivated paddy on about 1.91 lakh hectare land in eight tehsils of Gondia and on 1.78 lakh hectare in seven tehsils of Bhandara, they said.

With good rains in the last four months of the monsoon season, farming are hopeful of a good harvest. Some farmers have already started cutting their crops, but spells of showers in the last few days have worried them.

Some farmers said their paddy fields in Lakhni tehsil of Bhandara have got water-logged following the downpour. Gondia district agriculture superintendent Ganesh Ghorpade and his Bhandara counterpart Hindurao Chavan told PTI that farmers need not worry as of now, but if rains continue for some more time, then "things would get tougher". They have asked cultivators to delay the crop cutting work by five to six days and also keep a tab on rain prediction before harvesting the crop. -- PTI

Rainfall outlook for East India and West Coast until Wednesday morning. - The Weather Company

IMD maintains watch for fresh low

India Meteorological Department (IMD) has said that the withdrawal of the South-West monsoon has resumed from North-West India on Tuesday, with reduction in moisture content and cessation of rainfall over more parts of the region.

Thus, the monsoon has exited the whole of Rajasthan; more parts of Uttar Pradesh and Madhya Pradesh; most parts of Gujarat and some parts of the North Arabian Sea.

New challenger from Bay
How long the monsoon withdrawal progresses would depend on an ongoing rain session over East and Central India, and the predicted fresh spurt in rainfall with the formation of a fresh low-pressure area over the North Andaman Sea and adjoining Bay of Bengal by Friday.

The IMD has maintained a watch for it to move North-West towards and intensify as a depression by Saturday. This would bring enhanced rainfall to Andhra Pradesh, Telangana, Tamil Nadu, Puducherry and isolated heavy falls are also likely over Tamil Nadu and Telangana from Friday.

A prevailing low has weakened into a cyclonic circulation over South Coastal Odisha on Tuesday afternoon. But it has thrown open a trough back to East Bihar across the plains of West Bengal and signalled fairly widespread-to-widespread rain over East and North-East India, including hills of West Bengal and Sikkim on Tuesday.
Withdrawal of the monsoon from the North-West has allowed cool north-westerly (Arctic) winds to blow in from Pakistan/Afghanistan and cause the night temperatures to dip during the past few days, the IMD said.

Southwest Monsoon 2020

Courtesy good rains during the last week, the large rainfall deficiency of September has partially been covered and has now dropped from 30% to 13%. The pan India Monsoon tally remains above normal at 107% of LPA (Long-period average). The season’s average rainfall of 880mm has already been achieved ahead of time. Decent rains during this week also may take it further to 108 or even 109% for the second consecutive year.
The government has achieved record procurement of wheat and rice in the 2019-20 season. The high procurement was significant in view of COVID-19 pandemic, but the flip side of increase stocks do create storage problems as well as wastages. The prolonged state of the pandemic has led to a soft economy for most sectors excepting few. The alarming shrink of GDP by 23% is albeit worrisome but Agri-sector seems to have rescued from an otherwise possible disaster. In the backdrop of bountiful Monsoon, the allied sectors of seeds, fertilizers and tractor industry have fared exceptionally well. These are instrumental to offset partially the deep economic malaise brought on by the coronavirus pandemic. The tractor sales in the country have clocked over 35% year on year growth in July on the back of robust agricultural activities. The emerging trends of enhancing sales in the subsequent months go on to prove that spike seen early in the Kharif season was not just pent-up demand but vindicates sector’s growth potential. A 14% increase in Kharif sowing area has resulted in a 34% growth in fertiliser’s sales, indicating the Agri-economy has largely been untouched by the pandemic. The fertilisers’ sales rose for 9th month in a row and exceeded a recorded of 9million tonnes in July itself. A good Monsoon coupled with reverse migration of farm labourers appears to be heading for a bumper Kharif.
The movement of a low-pressure area across the central parts of the country is going to drench Maharashtra, Madhya Pradesh, Bihar, Jharkhand and West Bengal. Absence of weather activity over Northwest India may be construed as an indicator of withdrawal of Monsoon commencing from west Rajasthan shortly.
North India
Least weather activity is expected over the plains and hills as well during the week. It is an indication of Monsoon withdrawal pattern setting up in the next few days. Rise in the day temperatures and drop in the humidity levels are expected over most parts. Uttar Pradesh and Uttarakhand are expected to have scattered rains and thundershowers on most days of the week more intense on 23rd and 24th of September.
East and North-East India

The entire region is going to witness increased weather activity throughout the week. Fairly widespread rains and thundershowers along with lightning strikes are expected over Bihar, Jharkhand, and West Bengal. Heavy to very heavy rains are likely over Sikkim, sub-Himalayan West Bengal, Assam, Meghalaya, and Arunachal Pradesh. The state of Nagaland and Manipur will also experience intense rains and thundershowers on 21st and 22nd September and again between 25th to 27th September.
Central India
The movement of low- pressure area across central parts from Odisha to Madhya Pradesh will be resulting active to vigorous Monsoon conditions over Odisha, Chhattisgarh, Maharashtra, and Madhya Pradesh. The activity will be more intense in the first half of the week. Least weather activity will be experienced over Gujarat where it will remain confined to south Gujarat and adjacent parts of coastal Saurashtra. Intense rains are likely over Konkan including Mumbai on 21st and 22nd September.
Southern Peninsula
Telangana and coastal Andhra Pradesh will experience rain and thundershowers on most days but more intense on 21st 25th and 26th September. Coastal Karnataka and northern parts of Kerala will receive heavy rains at the beginning of the week 21st and 22nd of September and this activity will be mild during the rest of the week. The city of Bengaluru can expect some moderate showers during the second half of the week. Tamil Nadu will be the least active state during this period.
Delhi- NCR
Delhi NCR will experience hot weather conditions with temperatures in excess of 35 degrees at the start of the week. Mild thunderstorms and a few showers are expected between the 22nd and 24th of September. The signs of Monsoon withdrawal are appearing and is quite likely by the first week of October.
Cloudy sky with warm and sultry conditions are expected throughout the week. Also, short-duration light and patchy showers are likely in the evening and night hours during the second half of the week.
Air pollution
Since March, the air quality of Delhi and NCR has remained in ‘Satisfactory’ levels. There were various reasons for ‘Good’ or ‘Satisfactory’ air quality. Due to lockdown, almost all the factories and vehicular traffic remained absent until mid-July. Construction work also stopped. Due to scanty traffic and absence of commercial activities, smoke particles and dust particles remained very low in the lower atmosphere.
As the gradual unlock commenced air quality also start deteriorating. During last week, many areas of Delhi and NCR where in ‘Moderate’ category. But now, PM2.5 is at ‘Satisfactory’ level. PM10 is in ‘Moderate’ category in some pockets of Delhi and NCR. Reason for this spike in pollution levels can be attributed to increased traffic, the opening of factories and construction sites. Another important feature of the increase in pollution can be the weather. Since the last two weeks, weather of North-West India including Delhi and NCR is almost dry and hot.
Sometimes, prolonged dry spell associated with moderate westerly winds from Rajasthan leads to an increase in dust particle. That is why PM10 level is in the ‘Moderate’ category in some areas.
There may be light showers over Delhi NCR around September 22nd to 24th. Therefore, we do not expect much increase in pollution levels over Northwest India including Delhi for at least next 15 days.
After the withdrawal of Monsoon, by the first week of October, winds will be westerly and north-westerly for prolonged duration and stubble burning will also commence in the neighbouring states of Punjab and Haryana. Therefore, the chances of an increase in pollution levels are expected by the third week of October.

Monsoon 2020 to end with above-normal rainfall, Monsoon withdrawal to commence next week. Chances of an increase in pollution levels are expected by the third week of October


Three northern districts turn into Cherrapunji of Kerala with extremely heavy rainfall
Kozhikode, Kannur and Kasaragod districts received 344, 336 and 360 cm rainfall respectively during this period with Kozhikode registering 33 per cent excess rainfall, the highest in the state

This year the state has received 9 per cent above normal rainfall with 222.79 cm rain against the average of 204.92 cm

As the annual monsoon season in Kerala is drawing to a close, Kasaragod, Kannur and Kozhikode have become the Cherrapunji of the state by netting around 3500 mm rain against the normal average of around 2730 mm. The extremely heavy rainfall in these districts is attributed to the rise in low pressure formations over the Bay of Bengal.

Kerala used to get around 204.9 cm rain during the 120-day south west monsoon season. This year the state has received 9 per cent above normal rainfall with 222.79 cm rain against the average of 204.92 cm.
But Kozhikode, Kannur and Kasaragod districts received 344, 336 and 360 cm rainfall respectively during this period with Kozhikode registering 33 per cent excess rainfall, the highest in the state. In 2019 as well, Kozhikode, Kannur and Kasaragod districts recorded a rainfall of 346, 313, and 342 cm against the average of 257, 263, and 297 cm respectively.
P S Biju, joint director and head-in-charge, Indian Meteorological Department, Thiruvananthapuram, said, “Traditionally north Kerala used to net more rains than south Kerala as it lies in the track of the north-westerly wind coming from the Bay of Bengal. So rise in low pressure formations over Bay of Bengal is expected to have bearing on the weather in North Kerala, especially these districts,” he said.
In 2019, the Bay of Bengal witnessed a total of 13 low pressure formations during the south west and north east monsoon periods. In 2020, the south west monsoon period alone witnessed 13 low pressure formations over Bay of Bengal. And another low pressure will form in the Bay of Bengal by Friday. There are a lot of factors associated with the rise in low pressure formations, but this would bring more rains to northern Kerala and coastal Karnataka, said a senior scientist with the IMD.
Out of the 120-day long south west monsoon season, 55 days of Kerala's weather were influenced by the low pressures. There is also a rise in extreme rainfall days in the state. A day which receives 20 cm or more rainfall is considered an extreme rainfall day. Even in 2018, which witnessed the mega floods, the highest rainfall of 379 cm was recorded in Idukki against the average of 227 cm, which worsened the flood situation in the state.

Historic end for India's monsoon season

Updated 2338 GMT (0738 HKT) October 6, 2020

Heavy monsoon rainfall in Jaipur in August left this car caked in mud.

Heavy monsoon rainfall in Jaipur in August left this car caked in mud.

(CNN)India's famous monsoon has come to an end, and for the second consecutive year, the country observed an "excess" rainy season.

The rainfall average across the nation reached 109% of normal. This falls one percentage point shy of 2019's historic season of 110% above normal, which was the wettest monsoon season since 1994.
This makes the first time back-to-back rainy seasons had this large of a rainfall surplus since the 1950s. 2019 and 2020 rank as the second and third wettest season's respectively since 1990.
The India Meteorological Department classifies a monsoon as normal when total rainfall from June through September falls withing the range of 96-104% of average.
Totals between 104-110% of normal are considered "excess," while anything above 110% is designated as "large excess." Since monsoon records began in 1988, only the seasons of 1988, 1994 and 2019 were wetter than 2020.

A robust start
This year's monsoon began June 1 -- exactly on time -- in the southwest Indian state of Kerala. Simultaneously, Tropical Cyclone Nisarga formed in the Arabian Sea, off India's west coast. It made landfall south of Mumbai days later and pushed tropical moisture into central India.

More than 100 people killed during lightning strikes in India

The monsoon progressed quickly, and complete coverage of India by the monsoon happened on June 26 -- 12 days early.
The month ended with an excess rainfall of 18%, marking the first time since 2017 that June ended with a surplus of rain.
As the "wet season'" continued, the month of August ended with a large surplus at 27% above normal. This is the largest amount of rain to fall within that month in 44 years.

Factors that led to the record August rainfall
The north Bay of Bengal had a number of disturbances that funneled tropical moisture across the Indian Himalayan Region, which impacted six states. The heavy rain intensified river flooding across the region, causing landslides and killing dozens, and it prompted evacuations of thousands of residents.
There was also enhanced moisture from the Arabian Sea into western India due to increased upper-level winds. This led to the devastating landslide that killed dozens in Kerala and helped add to the record rainfall Mumbai experienced.
Mumbai observed nearly 3,700mm of rainfall since June 1, enough to catapult it into the second-wettest monsoon season on record, just short of the previous record set back in 1958.

Despite surplus, a water crisis looms
Normally, a monsoon surplus would be considered favorable for a country so dependent on its arrival. It brings an end to the extreme heat of India's dry season, where temperatures can hit 50 degrees Celsius (122 degrees Fahrenheit) in some areas.

Tens of thousands displaced in Assam as floods heap misery on pandemic stricken region

According to the National Institution for Transforming India, rain received from June through September makes up 70% of the country's annual rainfall, which irrigates crops and supplies drinking water.
This helps support the economy of the second-most populous country in the world -- 17% of India's GDP comes from agriculture, which employs half of its workforce.
Following five consecutive below-average seasons from 2014 to 2018, the surplus rainfall of 2019 and 2020 has helped replenish reservoirs. However, the country's population of over 1.3 billion still faces a long-term crisis as it heads toward outgrowing its water supply.

Tuesday, October 13: Parts of Maharashtra are set to experience rough weather conditions in the form of heavy rains, thunderstorms, lightning and strong winds for the next three days starting today, October 13.
As per the Indian Meteorological Department (IMD), a deep depression off the east coast of northeastern Andhra Pradesh will move westward while maintaining its power for the next five days. Moving at a maximum sustained wind speed of 55-65 kmph gusting to 75 kmph, it is expected to create wet conditions across east, central, west, and south India.
Under the influence of this system, heavy to very heavy falls are particularly expected across Maharashtra’s South Konkan & Goa, Madhya Maharashtra and Marathwada subdivisions on Tuesday.
On Wednesday, October 14, light to moderate rainfall is in the forecast at most places; with heavy to very heavy showers at a few places and extremely heavy rains (>20 cm per day) at isolated places over Madhya Maharashtra. Moreover, heavy to very heavy rainfall is also possible over isolated places of Konkan & Goa.
Owing to these rough conditions, the IMD has placed an orange alert (“be prepared”) over three subdivisions—Madhya Maharashtra, Marathwada, Konkan and Goa—for today.

Considering the weather is expected to aggravate over Madhya Maharashtra, a red warning—which instructs residents to “take action” and protect themselves from the rough conditions—has been placed over the central subdivision for this day. Meanwhile, Konkan & Goa and Marathwada will continue to remain under an orange alert.
The red warning for Madhya Maharashtra will be demoted to an orange alert on Thursday, as only heavy rains will be expected over the region by then.
Meanwhile, the met department has placed Vidarbha under a yellow watch for the next 48 hours (Tuesday and Wednesday), with the watch urging residents to ‘be updated’ of the local weather situation.
Over the course of this month, i.e. from October 1 to 12, Maharashtra has collectively received 41 mm rainfall. Within this time frame, its subdivisions Konkan & Goa (71 mm), Madhya Maharashtra (38.7 mm), Marathwada (47.4 mm), and Vidarbha (30.6 mm) have all recorded ‘normal’ rainfall figures.
