[Hindi] पूर्वी भारत में चल रही बारिश की गतिविधियाँ अब होंगी कम

चक्रवात मिचोंग का प्रभाव व्यापक वर्षा के रूप में देश के पूर्वी हिस्सों पर दिखाई दे रहा था। तटीय आंध्र प्रदेश पर भारी बारिश के बाद, चक्रवात कमजोर होकर एक दबाव क्षेत्र में बदल गया और उसके बाद छत्तीसगढ़ और आसपास के क्षेत्रों में कम दबाव का क्षेत्र बन गया। हमने बिहार झारखंड, पश्चिम बंगाल, ओडिशा, पूर्वी उत्तर प्रदेश, पूर्वी मध्य प्रदेश और छत्तीसगढ़ के कई हिस्सों में अच्छी बारिश देखी है।

निम्न दबाव का क्षेत्र कम चिन्हित हो गया है। बांग्लादेश के पूर्वी हिस्सों और आसपास के इलाकों पर एक चक्रवाती हवाओं का क्षेत्र बना हुआ है। देश के पूर्वी हिस्सों से बारिश की गतिविधियां काफी कम हो जाएंगी लेकिन पूर्वोत्तर भारत में अगले 24 से 48 घंटों तक बारिश जारी रह सकती है। पूर्वोत्तर भारत में बारिश की ये गतिविधियाँ हल्की तीव्रता की होंगी।

हमें अगले 8 से 10 दिनों तक पूर्वी और पूर्वोत्तर भारत में बारिश का एक और दौर आने की उम्मीद नहीं है। मौसम पूरी तरह शुष्क हो जाएगा, 9 दिसंबर से पूर्वी भारत में हल्के से मध्यम कोहरे की संभावना है। अगले दो से तीन दिनों के दौरान देश के पूर्वी हिस्सों में न्यूनतम तापमान में भी मामूली गिरावट हो सकती है।

Ongoing rain activities over East India to take a backseat now

The impact of Cyclone MICHAUNG was visible over eastern parts of the country in terms of widespread rainfall. After making landfall over coastal Andhra Pradesh, the cyclone weakened into a depression and subsequently in a low-pressure area over Chhattisgarh and adjoining areas. We have seen good rain over many parts of Bihar Jharkhand, West Bengal, Odisha, east Uttar Pradesh, east Madhya Pradesh, and Chhattisgarh.

The low-pressure area has become less marked. A cyclonic circulation is over eastern parts of Bangladesh and adjoining areas. Rain activities will reduce significantly from the eastern parts of the country but may continue over Northeast India for another 24 to 48 hours. These rain activities over Northeast India will be of light intensity.

We do not expect another spell of rain over East and Northeast India for the next 8 to 10 days. The weather will go completely dry. There are chances of shallow to moderate fog over East India from December 9. Minimum temperatures may also drop marginally over Eastern parts of the country during the next two to three days.

Wait for winters is becoming longer for Northwest and Central India

We are now in the second week of December and still, winter chill is not being felt anywhere in the plains of Northwestern and Central India. There are multiple factors for the absence of winter chill. Number one is the frequency and intensity of Western disturbances. We have not seen any active Western disturbance in October and November.

The first week of December has also gone almost dry for the western Himalayas. Due to the absence of Snow cover over the hills, the winds blowing from the Western Himalayas towards the northern plains are not very cold. Moreover, the feeble Western Disturbance is instrumental in altering the wind pattern. The normal flow of northerly winds is obstructed time and again due to the feeble Western disturbance.

Another factor is the lack of rain activities over North and Northwest India. Winter rains help in reducing the temperature and increasing the moisture. Due to the low temperature and increased moisture, moderate to dense fog appears over Northern Plains leading to a significant drop in day temperatures, which we have not seen until now.

Pollution is another factor, especially for Delhi-NCR and all the big cities. The pollutants trap the heat of the Sun and do not allow the temperature to drop. There may be a marginal fall in day and night temperatures during the next few days over Northwest and Central India but we do not expect a steep fall for at least during the next one week.

Fresh Western Disturbance although feeble to be seen next week over Western Himalayas

A feeble system in the form of a Western Disturbance is likely over the Western Himalayas next week. The system will reach the region around Dec 11. The spread and intensity will be mild and by December 13th, the rains will start receding. Mid and higher reaches will be the ones seeing rainfall activities.

Srinagar, Manali etc. may not see any rains as such. However, clouding may be there including Kullu, Manali, Dalhousie etc.

Mid and higher reaches may see some rain. Rain will start to clear on the 14th. The only impact it will have is a further fall in temperatures, which is single digit only at present. Fair weather conditions are expected for the plains as the system will largely affect mountains in terms of rain.

[Hindi] कोलकाता की बारिश अब होगी कम

कोलकाता में पिछले 24 घंटों में कुछ अच्छी बारिश की गतिविधियां देखी गई हैं। दरअसल, गुरुवार सुबह 8:30 बजे से पिछले 24 घंटों के दौरान दम दम हवाई अड्डे पर 34 मिमी और अलीपुर में 26 मिमी बारिश दर्ज की गई।

आम तौर पर, ये कोलकाता में बारिश के दिनों को नहीं मानते हैं क्योंकि इस दौरान बारिश की गतिविधियां बहुत आम नहीं होती हैं और केवल तब देखी जाती हैं जब बंगाल की खाड़ी में एक सिस्टम बनता है, जो इस बार चक्रवात मिचौंग के मामले में हुआ था।

पूर्वोत्तर भारत में भी सिस्टम के अवशेषों के कारण कुछ बारिश देखी गई है। सिस्टम कमजोर हो जाएगा और उत्तर-पूर्व की ओर बढ़ जाएगा। हम आज के बाद बेहतर मौसम की स्थिति की उम्मीद कर सकते हैं और आज के बाद कुछ खास देखने को नहीं मिलेगा।

Kolkata rains to take a backseat now

Kolkata has seen some good rainfall activities in the past 24 hours. In fact, during the last 24 hours from 8:30 am on Thursday, Dum Dum Airport saw 34 mm of rain and Alipore recorded rainfall to the tune of 26 mm.

Generally, these do not account for rainy days in Kolkata as rainfall activities are not very common during this time and are only seen when a system forms in the Bay of Bengal, which had been the case in terms of Cyclone Michaung this time.

Northeast India has also seen some rains on account of the remnants of the system. The system will weaken and move northeastward. We can expect better weather conditions after today and nothing significant is seen after today.

Chennai rains likely for the weekend, to reduce thereafter

Chennai rains have been consistent for quite some time now. Moreover, the month of December has seen intense rains courtesy of Cyclone Michaung. So much so that so far the Meenambakkam observatory has recorded 551 mm of rains while Nungambakkam saw 576 mm of rains. Moreover, the city saw double hundreds on two days in terms of three digit rains and excess of 300 mm on one of the days.

Now also, we do expect some rainfall activity in Chennai both today and tomorrow. These rainfall activities will be due to the Cyclonic Circulation over Comorin region while a low pressure area is also over Arabian Sea. Rains will reduce slightly on December 10 and significantly see a reduction on 11th.

Thereafter, we can expect rains to clear from Chennai completely and continue only over the extreme southern parts of the country.

Parts Of Darjeeling Witness Season's First Snowfall

Darjeeling in West Bengal, popularly known as the ‘Queen of Hills’ is reported to have snowfall, yesterday. Darjeeling city per se, has not received flakes of snow but surely was lashed with decent winter showers. The higher reaches of Darjeeling district’s Sandakphu, Phalut and Tiger Hills and surrounding areas experienced first snowfall of the season. Darjeeling town, as such, remain in queue for the ‘black magic’ event of witnessing white sheet, spread across the undulating black tea plantations and slopes of mountains.

Once a summer resort for the British Raj elite, Darjeeling is not frequented with snowfall and skips the event many a time during winters. Last time, the terminus of ‘Toy Train’ witnessed a freak occurrence of snowfall on 2 consecutive days. It gave tourists a rare chance to observe heavy and thick blanket of snow on 04^th& 05^thFebruary 2022, after nearly a gap of more than 10 years.

Darjeeling town has a modest elevation of 6,800 feet. It gives snowfall amiss, more often than not and pleases the tourists with such spectacular show, on an average, once in 5 years or even longer. Upper reaches of Darjeeling, such as, Sandakphu and Phalut have an elevation in excess of 12,000 feet and therefore witness repeated bouts of snow during winters. Even, Tiger Hills has fairly high altitude of about 9,000 feet and becomes a popular attraction to view snowfall.

The remnant of cyclone Michaung lashed most parts of West Bengal with moderate to heavy showers. This weather system coupled with an extension of trough linked with western disturbance moving across the mountains resulted little early snow along the popular trekking route Sandakphu-Phalut stretch. Both the systems are on the verge of clearing plains and mountains, both, in the next 24 hours or so. Weather conditions are expected to become better and pleasant, across the region of state of West Bengal.

Low Pressure Area Persist Over Arabian Sea, No Extreme Weather Likely

Low pressure area over southeast Arabian Sea and Lakshadweep region persist. Cyclonic circulation extends up to 18,000 feet, tilting southwest with height. Yesterday, the system became more intense for a while but receded again. An organized cloud cluster remains associated with the system. The low pressure moved slightly eastward towards Kerala coast but still adequately away from the coastline to cause any disturbing weather conditions.

The low pressure is likely to hold position for another 24 hours. As the system is quite low in latitude, between 6°-8°N, it is unlikely to strengthen. Further , the low pressure move away westward over equatorial latitudes of south-central Arabian Sea, increasing distance from the main land. Subsequently, the low pressure is likely to weaken and get manifested mainly as cyclonic circulation in the lower levels of atmosphere. The circulation is expected to head for west -central Arabian Sea towards Somalia coast.

The presence of low pressure over southeast Arabian Sea has influenced the wind pattern all along Kerala coast and adjoining Coastal Karnataka. Converging winds from the sea will rev up the northeast monsoon activity, lasting for about 48 hours. In addition to Kerala and Coastal Karnataka, decent showers may even reach South Interior Karnataka covering Bengaluru, Mysore, Mandya, Hassan and adjoining region.

No extreme weather conditions are likely over state of Kerala. Moderate rain and thundershowers with isolated places may have heavy rainfall. Lakshadweep Islands including Minicoy, Amini Devi and Agathi may have heavy rainfall in the next 48 hours.

Northeast Monsoon all set to become active now

Northeast Monsoon for two days over Tamil Nadu and Kerala has been weak courtesy of the cyclone that moved across. The change in weather pattern has especially been felt over the state of Kerala.

The system is likely to see light activity today. A circulation is to come up over the Comorin area and another system is over Southeast Arabian Sea and Lakshadweep. These embedded Circulations will increase rainfall activities over Kerala and Tamil Nadu.

Today, light rains will be seen over Kerala, and partly over Tamil Nadu. On December 8th, rainfall spread and intensity will increase, reaching parts of South Interior Karnataka including cities of Bengaluru, and Mysore as well as Mandya until 9th.

By December 10th, rainfall will start reducing. Starting December 11, extreme southern tip of Kerala and Tamil Nadu, Kanniyakumari etc will be the ones seeing good rains.

Rainy week observed for country courtesy Michaung, Pan India deficiency reduces

Rainfall activities have been on the higher side this week and has been the rainiest of the season. The Pan India deficiency stood at 19 percent at the end of November. However, as of now, due to intense rains between November 30th and December 6th, courtesy of Cyclone Michaung, the deficiency has reduced to 8 per cent.

The rainfall deficiency was on the higher side over South India, now this deficit has recovered from some parts. By the end of November, Coastal Andhra Pradesh and Yanam were rain deficient by 68 percent, Telangana by 78 percent, and Rayalaseema 61 percent. Now, Coastal Andhra Pradesh is rain deficient by 17 percent, Telangana by 57 percent, Rayalaseema by 27 percent, all of which have dropped significantly.

Tamil Nadu which was at -2 percent has now gone down to -6 percent as rainfall was only seen in the northern parts and that too coastal region while the interiors remained away from rainfall. The storm also took rains inside Vidarbha, Telangana, Jharkhand, Chhattisgarh, etc. The situation has now improved as the storm has moved towards East and Northeast India and will get filled soon.

Remnants of Michaung to give rain in Northeast India

Northeast India is all set to see some rain as the remnant of the storm is in proximity to the region. The remnant of the storm which weakened was earlier over parts of Jharkhand, Odisha and adjoining areas. A Cyclonic Circulation is seen close to the region.

This system will move further northeastward and will fill up over the land itself. With this, Manipur, Mizoram, Tripura and Southeast Assam, along with Meghalaya may see some good rains.

On the other hand, rainfall activities will be lesser over Arunachal Pradesh, Nagaland etc. In the next three days, rainfall will be in a decreasing order. Most rains are expected in the evening and night time. Days will be better as far as rains are concerned.
