Dynamics of Storm Tracks: A Linear Instability Perspective
Publisher: American Meteorological Society
Abstract: The instability properties of an observed seasonal mean flow are diagnosed in terms of (i) the local versus global instability of normal modes, (ii) the convective versus absolute instability of a pulse, and (iii) the ...
The Role of Orography in the Dynamics of Storm Tracks
Publisher: American Meteorological Society
Abstract: This paper investigates the role of the Northern Hemispheric orography in the maintenance of the winter storm tracks with a dry balance three-layer hemispheric model. First, the zonal winter-mean flow in 1982?83, together ...
Observed Variability in the Large-Scale Static Stability
Publisher: American Meteorological Society
Abstract: This paper reports on a diagnosis of nine years of temperature data for deducing the spatial and temporal variability in the static stability in four distinct ranges of time scale (seasonal cycle component, interannual ...
Statistical Downscaling Forecasts for Winter Monsoon Precipitation in Malaysia Using Multimodel Output Variables
Publisher: American Meteorological Society
Abstract: This paper compares the skills of four different forecasting approaches in predicting the 1-month lead time of the Malaysian winter season precipitation. Two of the approaches are based on statistical downscaling techniques ...
