Can Nor'wester events initiate stratospheric moistening?
TL;DR: The possibility of stratospheric moistening being initiated by deep convective Nor'wester events has been investigated over a period of three years spanning from 2013 to 2015 at a tropical location Kolkata, in India using radiosonde and satellite data as mentioned in this paper.

Observations of vertical rain structure using space borne and ground based radars at a Tropical location
Gargi Rakshit,Animesh Maitra +1 more
TL;DR: In this article, the vertical profile of the precipitation structure under varying propagation and rain conditions was studied using the radar data from the space and the ground to study the vertical profiles of radar reflectivity and rain rate, indicating the limitations of combining space based and ground based measurements.

Rain attenuation over earth space path from radar and propagation measurements at tropical location
TL;DR: In this paper, a simple approach is taken to study rain attenuation at various frequencies from propagation data and ground-based radar measurements at Kolkata, India, using the ITU-R model and the SAM model to estimate the slant rain rate and total attenuation from the vertical rain rate profiles.

Thermodynamic Changes in the Atmosphere Associated with Pre-monsoon Thunderstorms Over Eastern and North-Eastern India
TL;DR: In this article , the authors reviewed the atmospheric thermodynamic changes due to pre-monsoon thunderstorms over eastern and north-eastern India and found that the existence of small hills and plateaus in the area acts as triggering agents for thunderstorm initiation.
Proceedings ArticleDOI
Prediction of convective rainfall using multi-technique observations
TL;DR: In this paper, the brightness temperature at 31.4 GHz, the frequency having strong absorption due to liquid water, can give an estimate of rain accumulation with a prediction efficiency of ∼ 80 % and a lead time of 75 minutes.

Nowcasting Thunderstorms: A Status Report
TL;DR: In this paper, the authors reviewed the status of forecasting convective precipitation for time periods less than a few hours (nowcasting), and developed techniques for nowcasting thunderstorm location were developed in the 1960s and 1970s by extrapolating radar echoes.
Journal ArticleDOI
The life cycle of thunderstorm gust fronts as viewed with Doppler radar and rawinsonde data
TL;DR: In this paper, a horizontal roll detected in the reflectivity pattern resulting from airflow that is deflected upward by the ground, while carrying some of the smaller precipitation ahead of the main echo core of the squall line was detected.

Nowcasting severe convective activity over southeast India using ground‐based microwave radiometer observations
TL;DR: In this article, the feasibility of nowcasting convective activity is examined by using thermodynamic indices derived from the ground-based microwave radiometer (MWR) observations located at a tropical station, Gadanki (13.5°N, 79.2°E).
