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.

Performance and application of a multi-wavelength, ground-based microwave radiometer in intense convective weather
TL;DR: In this paper, the authors used a multi-wavelength, ground-based microwave radiometer to provide frequently updated (once every 5 minutes) thermodynamic profiles of the troposphere up to 10 km for the nowcasting of severe convective weather during a field experiment in Hong Kong in 2004.

A method to improve the accuracy of continuous measuring of vertical profiles of temperature and water vapor density by means of a ground-based microwave radiometer
TL;DR: In this article, a method for profile bias correction that significantly improves vertical temperature (T) and water vapor density (δwv) profile accuracy was proposed, using a corrector function that is applied at each T and WV level.
