Short-term prediction, or nowcasting, of rain rate derived from ground-based weather radar observations has become an important filed of research for several applications such as civil protection, water resource management and hydrometeorological alarming (Germann and Zawadzki, 2002). Most nowcasting techniques are based on advection approaches, solved by means of cross-correlation or optimizat...

The relationship between the multi-spectral cloud field characterization from the Advanced Very High Resolution Radiometer (AVHRR) and the rainfall intensities from the Advanced Microwave Sounding Unit-module B (AMSU-B) data were studied for a convective storm event, which occurred during the first 15 days of June 2007 over the Mediterranean. The cloud products exploited in this analysis, cloud...

Mesoscale convective systems (MCSs) in the tropics produce extensive anvil clouds, which significantly affect the transfer of radiation. This study develops an objective method to identify MCSs and their anvils by combining data from three A-train satellite instruments: Moderate Resolution Imaging Spectroradiometer (MODIS) for cloud-top size and coldness, Advanced Microwave Scanning Radiometer ...

One of the main challenges for meteorological and hydrological modelling is accurate rainfall measurement and mapping across time and space. To date, the most effective methods for large-scale rainfall estimates are radar, satellites, and, more recently, received signal level (RSL) measurements derived from commercial microwave networks (CMNs). While these methods provide improved spatial resol...

ABSTRACT: The author compared the capability of coherence information obtained from interferometric SAR (InSAR) by C-band SAR of ERS-1 and 2 and by L-band SAR of JERS-1 for the purpose of monitoring the changes of tropical rain forest due to deforestation. The test site was a southern part of Sumatra Island with 50 by 50 kilometers coverage. The several repeat-pass interferometric data pairs by...

Many investigators have used satellite data to derive rainfall intensity and to compare them with rain gauge data. However, there has always been a problem: what is the optimal time period for the two different types of data? A set of well-controlled data collected by ground-based dual-frequency microwave radiometers at the National Central University (24.98N, 121.18E) in Taiwan between January...

Based on daily meteorological data from 55 stations in eastern Gansu 1960 to 2017, the characteristics of drought process and precipitation heterogeneity were analyzed, relationship between was evaluated. Results showed that there 1–3 processes study area every year. Drought north-central regions more frequent than those other regions. Droughts mainly manifested as intra-seasonal droughts, espe...

Analyses of regional-scale synoptics and air-mass trajectories, local-scale atmospheric measurements (wind direction and speed, air temperature, dust load, SO 2 and NO x concentrations in the air, rain amount and intensity), and chemical and isotopic compositions of rainwater collected in the coastal city of Ashdod, Israel, were used to identify the various contributing sources to rainwater sal...
