A random forest algorithm for nowcasting of intense precipitation events
TL;DR: In this article, a random forest based machine learning algorithm is tested for nowcasting of convective rain with a ground-based radiometer and the results indicate that the proposed model is very sensitive to the boundary layer instability as indicated by the variable importance measure.

Nowcasting of deep convective clouds and heavy precipitation: Comparison study between NWP model simulation and extrapolation
TL;DR: In this article, an evaluation of convective cloud forecasts performed with the numerical weather prediction (NWP) model COSMO and extrapolation of cloud fields is presented using observed data derived from the geostationary satellite Meteosat Second Generation (MSG).

East-west coastal asymmetry in the summertime near surface wind speed and its projected change in future climate over the Indian region
TL;DR: In this paper, the authors investigated the behavior of various meteorological parameters during 1981-2010 to obtain any asymmetric variability of summertime near surface wind over Indian coastal boundaries, and found that no significant changes were obtained in the trends of surface pressure, surface relative humidity, 2-metre temperature and surface precipitation.

Evaluating the impact of climate change in threshold values of thermodynamic indices during pre-monsoon thunderstorm season over Eastern India
TL;DR: In this article, the authors analyzed thermodynamic indices variation over three sites of eastern Indian region: Bhubaneswar, Kolkata and Ranchi, associated with pre-monsoon thunderstorms for 20-year period (1987-2006) for Bhubaneh and Kolkatha and 15-years (1996-2010) for Ranchi.

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).
