Polarimetric radar observation of the melting layer during the pre-summer rainy season over South China

European Journal of Remote Sensing, 2023
The geometric and polarimetric characteristics of the melting layer (ML) during the pre-summer rainy season over South China (PRSC) are investigated from 389 S-band polarimetric radar volume scans. The existing ML detection algorithm is slightly improved,

Weather Prediction

International Journal for Research in Applied Science and Engineering Technology, 2022
Abstract: Weather maintains and sustains a extremely delicate balance of life on planet Earth. Climate conducts a totally critical function in many key production sectors, e.g., farming. global climate change with high charging nowadays, which is why old weather forecasts are becoming closer and fewer powerful and still be annoying.

A weather forecast model accuracy analysis and ECMWF enhancement proposal by neural network [PDF]

, 2019
This paper presents a neural network approach for weather forecast improvement. Predicted parameters, such as air temperature or precipitation, play a crucial role not only in the transportation sector but they also influence people's everyday activities.

Comparison of Atmospheric Turbulence Characteristics over Sea Surface and Land Surface before, during, and after Typhoons

Atmosphere, 2022
The goal of the paper is to reveal discrepancies of turbulent variables over different surfaces (sea, island, land) based on the measurements taken on three towers during (including before and after) seven typhoon episodes from 2008 to 2018.

Estimating 1min rain rate distributions from numerical weather prediction [PDF]

, 2017
Internationally recognized prognostic models of rain fade on terrestrial and Earth-space EHF links rely fundamentally on distributions of one-minute rain rates. Currently, in Rec. ITU-R P.837-6, these distributions are generated using the Salonen Poiares-
