An evaluation of the version-5 precipitation radar (PR; algorithm 2A25) and Tropical Rainfall Measuring Mission (TRMM) Microwave Imager (TMI; algorithm 2A12) rainfall products is performed across the Tropics in two ways: 1) by comparing long-term TRMM rainfall products with Global Precipitation Climatology Centre (GPCC) global rain gauge analyses and 2) by comparing the rainfall estimates from ...

The Tropical Rainfall Measuring Mission (TRMM) satellite has been in operation for more than 7 years and providing distribution of rainfall throughout the Tropics using microwave observation from the Precipitation Radar (PR) and the TRMM Microwave Imager (TMI). PR, the first space-borne precipitation radar, provides height information based upon the time delay of the precipitation-backscattered...

We study the initial value problem associated to the BenjaminOno equation. The aim is to establish persistence properties of the solution flow in the weighted Sobolev spaces Zs,r = Hs(R) ∩L2(|x|2rdx), s ∈ R, s ≥ 1 and s ≥ r. We also prove some unique continuation properties of the solution flow in these spaces. In particular, these continuation principles demonstrate that our persistence proper...

2. Chinese Academy of Meteorological Sciences, Beijing,10086 Abstract Using OTT-Parsivel Laser Particle Spectrometer at Nanjing in East China, several times heavy rain droplet scale & velocity spectral data aquatic from Mt. Lushan weather stations (elevation 1300meters) Compared to the plain deep convective clouds heavy precipitation, the rain droplet size distribution (DSD) with two elevation ...

The new generation of weather observatory satellites, namely Global Precipitation Measurement (GPM) constellation satellites, is the lead observatory of the 10 highly advanced earth orbiting weather research satellites. Indeed, GPM is the first satellite that has been designed to measure light rain and snowfall, in addition to heavy tropical rainfall. This work compares the final run of the Int...

In this paper, the effect of the structural properties and morphology of iron oxide product, have been studied in co-precipitation and hydrothermal methods. Also, the effect of adding CCl4 impurities and final annealing of the materials is taken into account. The more homogeneous particle size in hydrothermal method has been explained by the effect of adding CCl4 as impurities to prevent the co...

This study first focuses on comprehensive evaluating three widely used satellite precipitation products (TMPA 3B42V6, TMPA 3B42RT, and CMORPH) with a dense rain gauge network in the Mishui basin (9972 km) in ...

1.Introduction Use of proxy satellite observations for improving the model states of divergence, humidity and temperature has gained considerable impetus in the past one decade. Various researchers (Donner, 1998,Heckley et al, 1990, Krishnamurti, 1990) have used the satellite derived rainfall and moisture fields ameliorating the spin up problem in the tropics. Physical initialization methods (P...

The occurrences of precipitation, also commonly referred as rain, in the form of "convective" and "stratiform" have been identified to exist worldwide. In this study, the radar return echoes or known as reflectivity values acquired from radar scans have been exploited in the process of classifying the type of rain endured. The investigation use radar data from Malaysian Meteorology Department (...
