چکیده

[1] The probability density function of the drop diameter at the ground is investigated during stratiform and convective precipitation intervals at Darwin, Australia. We show how, after a renormalization procedure of the drop diameter, the empirical probability density functions of both types of precipitation collapse in a single curve, indicating the possible existence of an invariant distribution of the drop diameter at the ground.

Drop size distributions of tropical rain over south India

Drop size distributions (DSD) associated with tropical rainfall at Cuddalore in the south-eastern part of India have been measured by a JossWaldvogel disdrometer (RD–80 model) during September to November 2002. The rainfall data corrected for instrumental error, matches very well with rainfall rates measured by a self recording raingauge, at the same site. For further analysis of the DSD, the r...

Statistical Analysis of the Raindrop Size Distribution Using Disdrometer Data

The present study utilizes nine years of measurements taken from a Joss–Waldvogel disdrometer (JWD). From this dataset, thirty six rainfall events, were selected and categorized, respectively, in convective and stratiform types, according to specific criteria. Six statistical distributions namely the oneand two-parameter exponential, the twoand three-parameter lognormal and finally the twoand t...

Investigation of convective heat transfer, pressure drop and efficiency of ZnO/water nanofluid in alternating elliptical axis tubes

In this study, for the first time, the heat transfer and the pressure drop of zinc oxide nanoparticles in alternating elliptical axis (AEA) tube have been investigated experimentally. The zinc oxide nanoparticles were at volumetric concentrations 1% and 2%. The base fluid was heat transfer oil and the experiments were conducted at constant wall temperature. Also, the study was done in Reynolds ...

Origins of positive cloud-to-ground lightning flashes in the stratiform

7 [1] The origins of positive cloud-to-ground (+CG) 8 lightning in the stratiform region of a leading-line, 9 trailing-stratiform mesoscale convective system (MCS) are 10 investigated. Platforms include radars, NLDN data, and a 11 VHF 3-D lightning mapping system. This study examines a 12 small asymmetric MCS that occurred near the Colorado13 Kansas border in June 2000. In this storm 39 of the ...

Rainfall Microstructural Analysis for Microwave Link Networks: Comparison at Equatorial and Subtropical Africa

The quest to understand the variation of rainfall microstructures at subtropical and equatorial regions is vital to rain attenuation studies. In this study, point rainfall datasets obtained at Butare (2◦36′S, 29◦44′E) and Durban (29◦52′S, 30◦58′E), are compared at the reflectivity threshold of 38 dBZ. Joss-Walvogel (JW) distrometer measurements collected from these two locations represent physi...
