SCATSAT 1 – Scatterometer Satellite-1 or SCATSAT-1 was launched in 2016 and was developed by the Indian Space Research Organisation (ISRO) for weather forecasting, cyclone prediction, and tracking services for India. Read on to know more about this satellite at the linked article.
Bay of Bengal and Cyclone Yaas
Bay of Bengal sees approximately five times as many cyclones in comparison to the Arabian Sea. In addition, cyclones in the Bay are stronger and deadlier.
The Bay of Bengal is constantly fed by fresh water through giant rivers like the Ganga and the Brahmaputra. The river water that empties into the Bay warms up at the surface and rises up as moisture.
This makes it difficult for the warm layers of water to mix properly with the cooler layers of water below, keeping the surface always warm and ready to feed any potential cyclone over it. Cyclone Yaas is an outcome of the same process and had originated in the Eastcentral Bay of Bengal.
UPSC aspirants can also refer to the following information for exam preparation:
Temperate Cyclone (Extratropical Cyclones) – The term “Extra-tropical” signifies that this type of cyclone generally occurs outside the tropics with a latitude range between 30° and 60°. These cyclones are formed along the polar front and low-pressure systems with associated cold fronts, warm fronts, and occluded fronts.
Tropical cyclones – A tropical cyclone is a weather phenomenon that is essentially a rapidly rotating storm system with characteristics such as a low-pressure center, strong winds and thunderstorms that produce heavy rain, among others. Tropical cyclones are called by different names in different regions given below:
Hurricane – Atlantic
Typhoon – Western Pacific and the South China Sea
Willy-Willies – Western Australia
Cyclone – Indian Ocean
Bomb Cyclone – It is actually used by meteorologists to indicate a mid-latitude cyclone that intensifies rapidly. It is a massive winter storm hammering the coast, bringing strong winds, flooding, ice and snow
