NASA satellites covering typhoon Amphan headed for landfall
On Could 20, 2020 at 3:30 a.m. EDT (0730 UTC), the MODIS instrument that flies aboard NASA’s Aqua satellite tv for pc discovered coldest cloud high temperatures (yellow) in a big space round Amphan’s middle of circulation and alongside the coast on northeastern India. It was as chilly as or colder than minus 80 levels Fahrenheit (minus 62.2 Celsius). Credit score: NASA/NRL

NASA satellites have been offering forecasters with numerous varieties of imagery on Storm Amphan because it heads towards a landfall close to the border of jap India and Bangladesh on Could 20.


NASA-NOAA’s Suomi NPP satellite tv for pc offered seen imagery of Amphan and NASA’s Aqua satellite tv for pc offered an infrared view of the storm’s cloud high temperatures. Amphan was shifting north by means of the Bay of Bengal and forecast to make landfall in northeastern India close to Kolkata, which is simply west of the border with Bangladesh.

The Bay of Bengal is positioned within the northeastern a part of the Indian Ocean. The Bay is framed by India to the west, Bangladesh to the north, and Myanmar to the east.

On Could 19, the Seen Infrared Imaging Radiometer Suite (VIIRS) instrument aboard Suomi NPP offered a visual picture Amphan. The picture confirmed that Amphan coated the northern a part of the Bay of Bengal.

Tropical cyclones are made up a whole bunch of thunderstorms, and infrared information can present the place the strongest storms are positioned. They’ll try this as a result of infrared information offers temperature data, and the strongest thunderstorms that attain highest into the ambiance have the coldest cloud high temperatures. Convection is rising air that condenses and kinds the thunderstorms that make up a tropical cyclone. When it’s sturdy, it pushes larger into the troposphere (the layer of ambiance closest to Earth’s floor). The upper you go within the troposphere, the colder the air will get and colder cloud tops point out stronger storms.

On Could 20, 2020, at 3:30 a.m. EDT (0730 UTC) the Average Decision Imaging Spectroradiometer or MODIS instrument and the Atmospheric Infrared Sounder or AIRS instrument that each fly aboard NASA’s Aqua satellite tv for pc discovered coldest cloud high temperatures in a big space round Amphan’s middle of circulation and alongside the coast on northeastern India. It was as chilly as or colder than minus 80 levels Fahrenheit (minus 62.2 Celsius). NASA analysis has discovered that cloud high temperatures that chilly point out sturdy storms with the potential to generate heavy rainfall.

On Could 20 at 5 a.m. EDT (0900 UTC), Tropical Cyclone Amphan was positioned close to latitude 20.5 levels north and longitude 87.9 levels east, roughly, 129 miles south-southwest of Kolkata, India. Amphan was shifting to the north-northeast and had most sustained winds 85 knots (98 mph/157 kph). Amphan continued to carry on to Class 2 hurricane standing on the Saffir-Simpson Hurricane Wind Scale.

Forecasters on the Joint Storm Warning Heart mentioned that Amphan was weakening because it strikes north-northeast towards landfall. That landfall occurred within the morning hours of Could 20 Jap Daylight Time.

The Regional Specialised Meteorological Heart (RSMC) in New Dehli, India reported, “Amphan crossed West Bengal-Bangladesh coast between Digha (West Bengal) and Hatiya Islands (Bangladesh) throughout Sunderbans close to latitude 21.65 levels north and longitude 88.Three levels east between 1530 and 1730 [India Standard Time or] IST (6  and eight a.m. EDT) on Could 20 with wind velocity of 155-165 kph [96 to 103 mph].” Amphan is forecast to maneuver inland in a north-northeasterly course.
