| dc.description | The pre-monsoon season in India is commonly associated with thunderstorm and
dust storm activities. Its effects or damaging potential depends on the vertical
development and growth of the weather system and brings middle tropospheric air
down to the surface. Sudden downburst is generally hazardous in nature and it’s
impact depends on the size & area of occurrence, demography, population density etc.
These events during pre-monsoon or even monsoon are very common over hilly areas
where sudden downpour in a very short time can affect the society. Wind index
(WINDEX) is the potential of air mass available over the area at a particular instant of
time which can cause sudden downpour or microburst. | en_US |
| dc.description.abstract | Changing climate is global concern now-a-days and many organizations are working
together to discuss, analyze and interpret the information in more meaningful way.
The conventional information is limited and data sparse regions are mainly depending
on the remote sensing (satellite or radar) observations. This remote sensing
information’s are associated with errors and needs to validate. In this present study IR
sounder data Wind Index onboard on INSAT-3DR satellite has been validated with in-
situ ground-based Radiosonde data. It is found that the results are agrees fairly well
with negative bias of satellite data. Further this analysis is found to be very useful in
diagnosing the thunderstorm or dust storm events in more meaningful way at the time
of wind gusts etc. Therefore, satellite derived WINDEX is very useful in aviation
forecasting especially for short duration or helicopter operations. The WINDEX data
retrieved from clear sky pixels of INSAT-3DR sounder data have been utilized in
recent Delhi NCR thunder squall case (30th May -2022) and WINDEX values shows
>45 KT at least 3-4 hour hours prior. | en_US |
