Lightning characteristics in India are examined with satellite-based Imaging Sensor (LIS) and ground-based Indian Detection Network (ILDN). LIS observations indicated that synoptic weather systems major contributors of lightning hotspots. Western disturbances (mid-tropospheric extratropical origin) were the greatest contributor Himalayas (93%), tropical cyclonic storms low-pressure (oceanic key...

Hydrographic data are analyzed for the broad continental shelf of Bellingshausen Sea, which is host to a number rapidly thinning ice shelves. The flow warm Circumpolar Deep Water (CDW) onto observed in two major glacially carved troughs, Belgica and Latady troughs. Using ship-based measurements potential temperature, salinity, dissolved oxygen, collected across several coast-to-coast transects ...

the quality of pressure distribution over the atmosphere of the sea level and geopotential altitude at different atmosphere layers affect on many climate and meteorology phenomena of the earth surface. one of the important meteorology phenomenon is the occurrence of frost phenomenon especially late spring frost. in this surrey, occurring late spring frost days and minimum temperature during the...

Pure tones of 1, 2, 4, 8, and 10 kHz were broadcast from the body of a dead starling Sturnus vulgaris, and sound pressure levels were measured through 360” in three planes. At high frequencies (8 and 10 kHz) there were large troughs in sound pressure levels in the acoustic “shadow” of the bird’s body. A physical model based on sound interference phenomena predicts similar patterns of sound pres...

Introduction: We have identified numerous examples of anomalous trough stratigraphy within the North Polar Layered Deposits (NPLD). According to the standard model of NPLD stratigraphy [1], troughs can be divided into three main units: (1) Layered Terrain, which exhibit fine-scale laminae upon equatorward-facing (EWF) trough slopes; (2) Banded Terrain, more diffuse layers located on poleward-fa...

1. introduction dust storm is an important atmospheric phenomenon. it has important environment, health, economic and social activities due to penetration of suspended particles of dust to the atmosphere. measurements resulting from earth and satellite stations show the fact that particles of dust in storms, remain in the nature for a long time. they can get far away by wind, hundreds of kilome...

Vancomycin trough concentrations should be measured within 30 min of the next dose, but studies have shown that troughs are often measured too early, producing erroneous results that could lead to dosing errors. The purpose of this study was to identify the frequency of early trough measurements and to evaluate whether pharmacokinetically extrapolating mistimed concentrations may locate sub-the...

This study was carried out using two sets of numerical weather forecast data and flight reports for Clear Air Turbulence (CAT) over Iranian Plato to find atmospheric flow patterns favorable to the formation of CAT. The numerical data include five months of AVN analysis with horizontal resolution of 1 degree(about 100 km) and four months forecast data of MM5 model with resolution of 50 km. Impor...
