Abstract: The winter of 1941?42 is known as the coldest European winter of the 20th Century. The temperature was much below normal from the beginning of January until the end of March 1942. Blockings and cut-off lows were frequent, ...

Abstract: An explicitly integrated primitive equation grid-point model is used as a tool to study the impact of some variables on the hemispheric average precipitation rate in the model. The experiments show that the model needs 15 ...

Abstract: A primitive equation grid-point model is used as a tool to study the impact of nonlinear normal mode initialization on the nonconvective precipitation rate in the model. It is found that the precipitation rate is affected ...

Abstract: Planetary-scale free Rossby waves present in the earth?s atmosphere propagate toward the west. Pressure torques varying in time then arise as a consequence of unequal pressure on the eastern and western sides of mountains ...

Abstract: The possible relation between blocking-type flow patterns in the atmosphere and large-scale traveling waves has been investigated. A 30-yr time series of observational 500-hPa geopotential-height data was used to study the ...
