A lightning threat index for South Africa using numerical weather prediction data
… index, precipitable water, equivalent potential temperature, relative humidity and air temperature. This study identifies the parameter from each of the six groups capable of predicting the occurrence of lightning over southern Africa the best during spring and summer by means of stepwise …

Wind and temperature in a glacierised Himalayan valley, and their controlling mechanisms
… such as the local valley wind regimes and the lapse rates of near-surface temperatures, are poorly understood in the HKKH. This thesis aims to improve understanding of the valley wind regime and temperature lapse rate for the glacierised Dudh Koshi River Basin in the Nepalese Himalaya, which …

Influence of summer snowfall on discharge emanating from the Gangotri glacier
… Himalayas. This was achieved by collating air temperature, precipitation and discharge data for the study area. Data were used to determine the hydrological regime within catchment and to establish the general influence that air temperature and precipitation have on discharge, using regression …

Monthly mean vertical motions over the Pacific Ocean
It is the purpose of this paper to compare vertical velocity with satellite observed cloud distribution in the tropics, especially with (1) the intertropical maximum cloud band in the Northern Hemisphere paralleling the equator and about 5 degrees north of it throughout the year, (2) the occurrence …

Stellar occultation studies of Saturn's upper atmosphere
… numerical inversions. These analyses show that temperatures in the 1-10 [mu]bar range can vary significantly as a function of season and latitude, ranging from 121 to 160 K, in accordance with radiative transfer models for the atmosphere. We also search for evidence of gravity wave saturation in …

Tropical orographic rainfall regimes according to the tropical rainfall measuring mission
… cross-barrier flow, mean virtual potential temperature, lapse rate of the mean virtual potential temperature, Brunt-Väisälä Frequency, and the moist Froude number. The variables and parameters are then organized into regimes specific to each individual region of complex terrain. The Tropical …

Atmospheric controls on soil moisture-boundary layer interactions
… and rainfall is likely when the early morning temperature lapse rate in this region is dry adiabatic; a positive feedback is likely when it is moist adiabatic; and when there is a temperature inversion in this region, deep convection cannot occur, independent of the soil moisture. Additionally, …

Understanding the Lowermost Stratosphere in Current and Future Climates: Composition, Definition, and Tropopause-Overshooting Convection
The troposphere and the stratosphere are two separate layers of the atmosphere whose dynamics, composition, and chemistry are fundamentally different. This leads to the upper troposphere and lower stratosphere (UTLS) being a complex region of the atmosphere that is critically important to both …
