Explaining discrepancies in passive microwave cloud-radiation databases in microphysical context from two different cloud-resolving modelsMeteorology and Atmospheric Physics - Tập 101 - Trang 127-145 - 2008

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
Eine quantitative Niederschlagsprognose mittels dynamischer PrädiktorenMeteorology and Atmospheric Physics - Tập 18 - Trang 313-330 - 1969
Georg Skoda
Sechs Prädiktoren dynamischer Art (Windstärke, Windrichtung in 500 mb, relative Vorticity, zeitliche Änderung der relativen Vorticity, Winddrehung mit der Höhe und Windgeschwindigkeit in Bodennähe) werden zum Prädiktanden Tages-bzw. Nachtniederschlag in Beziehung gesetzt. Nach paarweiser Gruppierung der Prädiktoren lassen sich auf graphischem Wege prognostisch verwertbare Diagramme konstruieren.
Soil occupation and atmospheric variations over Sobradinho Lake area. Part two: a regional modeling studyMeteorology and Atmospheric Physics - Tập 94 - Trang 115-128 - 2006
M. F. Correia, M. A. F. da Silva Dias, M. R. da Silva Aragão
The impact of the changes on soil cover and land use brought about by the construction of the Sobradinho Dam in the semi-arid region of the São Francisco River Hydrographic Basin is analyzed by means of a numerical model RAMS. Disregarding the influence of a large scale flow, a set of factors were responsible for the creation of a rather complex circulation system that includes mountain-valley win...... hiện toàn bộ
A note on smoke concentration in urban Athens, using data measured by two different methodsMeteorology and Atmospheric Physics - Tập 55 - Trang 215-221 - 1995
I. C. Ziomas, A. G. Paliatsos, L. G. Viras, C. S. Zerefos
The relationships between smoke concentrations, measured at two monitoring stations in Athens by the ASTM (American Society for Testing and Materials) and the OECD (Organization for Economic Co-Operation and Development) methods are studied by using a sample of 738 mean daily values of simultaneous measurements during the period 1984–1986. It is shown that an exponential model, different for each ...... hiện toàn bộ
Climate sensitivity studies of the Greenland ice sheet using satellite AVHRR, SMMR, SSM/I and in situ dataMeteorology and Atmospheric Physics - Tập 51 - Trang 239-258 - 1993
K. Steffen, W. Abdalati, J. Stroeve
The feasibility of using satellite data for climate research over the Greenland ice sheet is discussed. In particular, we demonstrate the usefulness of Advanced Very High Resolution Radiometer (AVHRR) Local Area Coverage (LAC) and Global Area Coverage (GAC) data for narrow-band albedo retrieval. Our study supports the use of lower resolution AVHRR (GAC) data for process studies over most of the Gr...... 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
K.-Y. Kim
¶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
