The Indo-Gangetic Plainis located South and upwind of the Himalayan foothills. The region is associated with high aerosol loading, much of which is black carbon and dust, and thus provides an opportunity for studying how aerosol  affects extreme rainfall events, particularly when air mass is forced from a low elevation to a higher elevation as it moves over rising terrain technically called orographic forcing.

A team of researchers from National Institute of Technology Rourkela, Leipzig Institute for Meteorology (LIM), University of Leipzig, Germany, Indian Institute of Technology Madras, Indian Institute of Technology Kanpur supported by the Department of Science & Technology, Government of India under DST Climate Change program have highlighted the crucial role of the aerosol direct radiative effect on high precipitation events over the Himalayan region. The findings of the current work have been accepted for publishing in the scientific journal ‘Atmospheric Chemistry and Physics’ recently.

They showed that particulate emissions can alter the physical and dynamical properties of cloud systems and, in turn, amplify rainfall events over orographic regions downwind of highly polluted urban areas.

The study used 17 years (2001–2017) of rainfall rate, aerosol measurements called aerosol optical depth (AOD), meteorological reanalysis fields such as pressure, temperature, and moisture content at different altitudes are used to compute the thermodynamic variable “moist static energy” and outgoing long-wave radiation from Indian region to investigate high precipitation events on the foothills of the Himalayas. The team found clear associations between high precipitation events, high aerosol loading, and high moist static energy (MSE) values (Moist static energy of an air mass includes the potential energy due to its height above the ground and the latent heat due to its moisture content). The findings also highlight the crucial role of the radiative effect of aerosol on high precipitation events over the Himalayan region.

The results of the study indicate that aerosols can play a vital role in exciting high precipitation (HP) events over the Himalayas during the monsoon season. Thus, aerosols, including chemistry, are essential to consider when forecasting HP events over the Himalayan region in regional modelling studies.

The intensity of the rain is likely to reduce from Wednesday, with the weather bureau issuing a yellow alert for Mumbai.

Moderate to a few intense spells, accompanied by thunderstorm and lightning, hit parts of Mumbai and neighbouring areas on Monday evening. Between 5 pm and 7 pm, Bandra recorded 20.2 mm, Santacruz 16.6 mm, Ram Mandir 28.5 mm and Thane and Kalyan between 40 mm to 70 mm of rainfall.

For the coastal districts – Raigad, Ratnagiri and Sindhudurg – IMD has predicted extremely heavy rainfall (above 204 mm) on Tuesday.

“Given the low pressure area formed in north-west Bay of Bengal, parts of Konkan-Goa and adjoining ghat areas of Madhya Maharashtra are very likely to receive enhanced rainfall activity during the next two days with a gradual reduction thereafter,” said IMD.

With the formation of the low pressure area, south-westerly monsoon flow is expected to strengthen, leading to an increase in rainfall activity in the state.

According to the forecast for Mumbai, occasional gusty winds with speed reaching 45 kmph to 55 kmph, along and off the coast, may damage vulnerable and temporary structures. With heavy to very heavy rainfall warning, flooding and traffic disruptions are also likely on Tuesday.

After above-average rainfall in August, Palghar, Mumbai and Raigad recorded deficient rainfall in September. Mumbai received 123.6 mm of rain between September 1 and 21, which is 46 per cent below the average (229.7 mm) for the same period. It had received 3261.3 mm rain since June 1, which is 55 per cent above the average mark.

• The monsoon trough is active and near to its normal position. It is likely to be active and meandre around its normal position during next 4-5 days.
• Convergence of strong southerly/southwesterly winds from Arabian sea over northwest and adjoining central India very likely during next 3-4 days.
• An east-west shear zone runs along Latitude 18ºN in the middle tropospheric levels and likely to persist during next 2 days.
• A Low Pressure Area is very likely to develop over Northwest Bay of Bengal around 13th August leading to strengthening of the monsoon flow over northern parts of the West coast and over the North Bay of Bengal during 13th-15th August, 2020.

Under the influence of the above meterological conditions:

i. Fairly widespread to widespread rainfall with heavy to very heavy falls at isolated places very likely over major parts of Northwest India (Western Himalayan region, Punjab, Haryana, Chandigarh & Delhi, Uttar Pradesh) during 12th-15th August 2020.

ii. Fairly widespread to widespread rainfall with heavy to very heavy falls at isolated places very likely over Gujarat state, East Rajasthan, Madhya Pradesh and Vidarbha during 11th -15th August and over northern parts of Konkan & Goa, during 14th-15th August. Isolated extremely heavy falls also likely over Gujarat state & East Rajasthan.

iii. In association with low pressure area, fairly widespread to widespread rainfall with heavy to very heavy falls at isolated places very likely over Odisha and Chhattisgarh during 14th-16th August 2020.

heavy rainfall was likely in isolated places of coastal Maharashtra, including Mumbai, till August 15.
While Mumbai is expected to receive light to moderate showers, neighbouring districts of Thane, Palghar, Raigad and Ratnagiri may witness heavy rains at isolated places, an IMD official said.

“A similar forecast has been issued for Pune, Kolhapur and Satara districts as well till August 15. However, districts in North Maharashtra, Marathwada and Vidarbha may receive light to moderate rainfall in the same period,” the official said.

KS Hosalikar, the Deputy Director General of Meteorology, India Met Department, Mumbai, has tweeted the amount and intensity of rainfall in Mumbai and the suburbs in the last 24 hours. Colaba, Kandivali, Borivali, Mira Road, Bhayandar, Chembur and Nerul are some of the localities that recorded very heavy rainfall.

Mumbai and around rains in last 24 hrs on 28th July.

Mr Hosalikar also said, on August 1, Mumbai, Thane and the Konkan coast are likely to receive very heavy rainfall.

Skymetweather said isolated spells of rain might continue for the next 3 to 4 days over Mumbai and suburbs, but the overall intensity of rain would remain subdued. Parts of financial capital Mumbai, including Dadar and Hindmata areas, faced severe waterlogging following heavy rainfall in the region. This caused severe inconvenience to people who were out on the streets headed towards their work.

Meanwhile, heavy traffic congestion was seen in the Vashi area of Navi Mumbai after a spell of rain.

Several vehicles were seen wading through knee deep water on Mumbai roads, while a tree fell on a car in Navi Mumbai.

Several parts of the Mumbai city had witnessed water logging even on Sunday troubling commuters. Similar scenes were seen in Navi Mumbai areas on Tuesday.

According to the IMD’s forecast for its Worli station, moderate rains are expected in the area with the sky remaining generally cloudy through the day. A minimum temperature of 24 degrees Celsius and a maximum of 30 degrees Celsius has been predicted for tomorrow. It projects persistent rains in the city beginning July 12.
