Abstract: The paper describes the techniques developed at Poona for the measurement of electrical potential gradient in the free atmosphere and discusses the results of the observations made over Poona during 1953?1958. The day-to-day ...

Abstract: An attempt is made in this paper to formulate the transport of hydrogen in the earth's upper atmosphere as a Monte Carlo problem. The relevant details of the technique adopted are given. The capability of the technique to ...

Abstract: The chemiluminescent reaction responsible for the nightglow in the sodium D lines is embedded in the complex kinetics of an oxygen-hydrogen atmosphere. Various possibilities of identifying this reaction from observational ...

Abstract: A spectral theory is developed for the solar semidiurnal tides in an atmosphere with background zonal winds. According to this theory, the vertical structures of the spectral components of the tide are governed by a set ...

Abstract: Classical and nonclassical model calculations have been performed for the solar semidiurnal tidal oscillations in the earth's atmosphere, for prescribed basic-state parameters and heating functions appropriate for the ...

Abstract: The hydroxyl bands in the glow emanating from the earth's upper atmosphere are chemically excited. The two possible precursor reactions are O3+H?OH*+O2 and O2*+H?OH*+O. Arguments are advanced in this paper to show that the ...

Abstract: Calculations of the semidiurnal atmospheric tide at solstice using improved heating rates are presented. The heating rates for solar absorption by water vapor are based on a global water vapor distribution (Jenne, 1969, ...

Abstract: Observations from two Doppler sodars and a radar wind profiler have been used in conjunction with data from a rawinsonde station and a mesoscale surface observation network to conduct a case study of a gravity current ...
