Multi-technique observations on precipitation and other related phenomena during cyclone Aila at a tropical location
TLDR
In this article, the strong convective activities manifested through rainfall during the cyclone were studied with multi-technique observations involving micro rain radar, disdrometer, rain gauges, and a Ku-band satellite signal receiving system.Abstract:
A severe cyclone, named Aila, passed over Kolkata on 25 May 2009. The strong convective activities manifested through rainfall during the cyclone were studied with multi-technique observations involving micro rain radar, disdrometer, rain gauges, and a Ku-band satellite signal receiving system. A number of features of precipitation, namely the presence of large rain drops, the large vertical extent of the precipitating layer, an unusual enhancement of cross-polar component, and strong scintillations of the co-polar component of the satellite signal due to strong turbulences associated with the cyclone, were observed. This study leads to a more comprehensive understanding of the precipitation associated with a cyclonic storm.read more

Geographically weighted regression based methods for merging satellite and gauge precipitation
TL;DR: In this article, a three-step satellite and gauge precipitation merging method was formulated to improve the spatial resolution and quality of satellite precipitation, and eight algorithms, a combination of two geographically weighted regression methods and four weighting functions, were developed to merge CMORPH (CPC MORPHing technique) precipitation with station observations on a daily scale in the Ziwuhe Basin of China.
Raindrop Size Distribution Measurements in Tropical Cyclones
TL;DR: In this article, the authors studied the characteristics of raindrop size distribution in seven tropical cyclones through impact-type disdrometer measurements at three different sites during the 2004-06 Atlantic hurricane seasons.

Spatial downscaling of TRMM 3B43 precipitation considering spatial heterogeneity
TL;DR: In this article, a new downscaling method considering this spatial heterogeneity was proposed to downscale version 7 of the TRMM 3B43 precipitation product, which assumes that the relationship varies spatially but is the same in a local region.

Jayalakshmi Janapati,Balaji Kumar Seela,Balaji Kumar Seela,M Venkatrami Reddy,K. Krishna Reddy,Pay Liam Lin,T. Narayana Rao,Chian-Yi Liu +7 more
TL;DR: In this paper, the authors used a laser-based disdrometer at two different locations [Kadapa (14.47°N, 78.82°E) and Gadanki (13.5°N and 79.2°E)] in semi-arid region of southern India to investigate the raindrop size distribution characteristics in before landfall (BLF) and after landfall (ALF) induced precipitations.

Anil Deo,Kevin Walsh +1 more
TL;DR: In this paper, the authors compared the rainfall drop size distribution (DSD) during the passage of seven tropical cyclones over Darwin is compared and contrasted with that associated with non-tropical cyclone (non-TC) events, using the impact disdrometer data at the Darwin Atmospheric Radiation and Measurement (ARM) site.

On the investigation of hidden periodicities with application to a supposed 26 day period of meteorological phenomena
TL;DR: Most often, small periodic variations are hidden behind irregular fluctuations, and their investigation then becomes a matter of considerable difficulty.

Classification of Precipitating Clouds in the Tropics Using 915-MHz Wind Profilers
TL;DR: In this paper, an algorithm was developed that classifies precipitating clouds into either stratiform, mixed stratiform/convective, deep convective, or shallow convective clouds by analyzing the vertical structure of reflectivity, velocity, and spectral width derived from measurements made with the vertical beam of a 915-MHz Doppler wind profiler.
