Mesoscale Cloud Resolving Models (CRMs) are often used to generate descriptions of the microphysical properties of precipitating clouds for the purpose of guiding precipitation retrieval algorithms designed for satellite-borne passive microwave radiometers. However, CRMs were not originally designed for that purpose. Notably, individual CRMs have adopted different bulk microphysical schemes to opt...... hiện toàn bộ
On the origin of upper tropospheric cyclonic vortices in the South Atlantic ocean and adjoining Brazil during the summerMeteorology and Atmospheric Physics - Tập 37 - Trang 11-16 - 1987
V. B. Rao, J. P. Bonatti
The origin of upper tropospheric cyclonic vortices over the South Atlantic and adjoining Brazil is discussed. Calculations of the barotropic energy exchange term based on observations indicated that in the mean, and during some days, zonal kinetic energy gets converted into eddy kinetic energy. This suggests the occurrence of barotropic instability. Examination of zonal winds for barotropic instab...... hiện toàn bộ
Investigation of ENSO variability using cyclostationary EOFs of observational dataMeteorology and Atmospheric Physics - Tập 81 - Trang 149-168 - 2002

¶The variability of El Niño-Southern Oscillation (ENSO) on all time scales, ranging from months to decades, has been studied from the perspective of sea-surface temperature anomaly (SSTA), sea-level pressure anomaly (SLPA), and surface wind anomaly (SWA) fields using a statistical tool called cyclostationary empirical orthogonal function (CSEOF) analysis. The analysis indicates that a significant ...... hiện toàn bộ
The anomalous weather parameters that lead to the extreme rainfall of Kerala in August 2018Meteorology and Atmospheric Physics - Tập 135 - Trang 1-13 - 2023
S. S. Suneela, Basil Mathew, S. Sureshkumar
Extremely heavy rainfall occurred over Kerala, southwest coast of India, during mid-August 2018 resulting in devastating floods. This flood may be called “the flood of the century” as the state has not experienced a flood of this magnitude since the 1924 flood. The rainfall over Kerala during June, July and August 2018 was 15%, 18% and 164% above normal. To examine the reasons for this anomalous p...... hiện toàn bộ
Pre-monsoon rainfall and surface air temperature trends over India and its global linkagesMeteorology and Atmospheric Physics - Tập 131 - Trang 1005-1018 - 2018
Palash Sinha, M. M. Nageswararao, Guru Prasad Dash, Archana Nair, U. C. Mohanty
An evidence of a changing climate is already sensed in India where there is a large diversity from region to region and from season to season. The rainfall pattern in the pre-monsoon (March–April–May) season is important as it helps in determining many crop-related activities in many parts of the country. In the present study, an attempt is made to analyze the current trends in pre-monsoon season ...... hiện toàn bộ
An astronomical determination of the turbidity parameters of the atmosphereMeteorology and Atmospheric Physics - Tập 41 Số 1 - Trang 13-18 - 1989
Asteriadis, G., Tsioumis, A. C.
A number of star observations, which were carried out at the Stephanion Observatory located in southern Greece, was analysed in order to determine the turbidity parameters α and β of the atmosphere. The method used is a modification of the de Vaucouleurs' method (1965) employing least squares analysis. The results which were found for these parameters are bounded in the expected limits.
