Radon is being measured continuously in spring water and soil-gas at Badshahi Thaul Campus, Tehri Garhwal in Himalayan region by using radon Emanometer since December 2002. An effort was made to correlate the variance of radon concentrations in spring water and soil-gas with meteorological parameters at the same location. The main meteorological parameters that affect the radon emanation from h...

Mosquito-borne diseases particularly malaria is becoming most dreaded health problems in the Coastal Blocks of Ramanathapuram District, Tamilnadu, India. In Coastal Blocks of Ramanathapuram District, malaria is seasonal and unstable, causing frequent epidemics. For transmission of malaria parasite, climatic factors are important determinants such as rain fall, temperature relative humidity and ...

Measurements using the 2-D video disdrometer (2DVD) taken during a heavy rainfall event in Huntsville, Alabama, are analysed. The 2DVD images were processed to derive the rain microstructure parameters for each individual drop, which in turn were used as input to the T-matrix method to compute the forward and back scatter amplitudes of each drop at C-band. The polarimetric radar variables were ...

Issue No. 2, Fall 2002 www.spacejournal.org Page 1 of 29 A Prediction Model that Combines Rain Attenuation and Other Propagation Impairments Along EarthSatellite Paths Asoka Dissanayake, Jeremy Allnutt, Fatim Haidara Abstract The rapid growth of satellite services using higher frequency bands such as the Ka-band has highlighted a need for estimating the combined effect of different propagation ...

Two simple heuristic model formulations for warm rain formation are introduced and their behavior explored. The first, which is primarily aimed at representing warm rain formation in shallow convective clouds, is a continuous collection model that uses an assumed cloud droplet size distribution consistent with observations as the source of embryonic drizzle drops that are then allowed to fall t...

Cheatgrass (Bromus tectorum L.) is a winter annual weed that presents a serious obstacle to rangeland restoration in the Intermountain West. The objective of this study was to evaluate factors regulating the size and persistence of cheatgrass carryover seed banks on semiarid sites in western Utah. We prevented current-year seed production in each of four habitats, then tallied emerging seedling...

Rain is a condition where water droplets fall from clouds to the earth. In life, presence of rain highly anticipated, can help people who have profession as farmers. that occurs on large scale will really provide obstacles for community, in addition hampering activities or especially those carried out outdoor also cause disaster community form flooding. Estimating very important, knowing whethe...

During heavy rain on 1–2 June 2015 in central China, the Wuhan mesosphere–stratosphere–troposphere (MST) radar was applied to record atmospheric responses with a 30 min period. According vertical gradient of echo power above 500 hPa, tropopause height could be determined by MST detection. The descent clearly observed few hours before rain, and then recovered usual heights during rain. observati...
