Resonant Continuum Modes in the Eady Model with Rigid Lid
Publisher: American Meteorological Society
Abstract: The Eady model with rigid upper lid is considered. The resonant, linearly amplifying solution that exists in the situation of neutral normal modes when an infinitely thin potential vorticity (PV) perturbation is located ...
Seasonal Modulations of the Active MJO Cycle Characterized by Nonlinear Principal Component Analysis
Publisher: American Meteorological Society
Abstract: novel methodology is presented for the identification of the mean cycle of the Madden?Julian oscillation (MJO) along the equator. The methodology is based on a nonlinear principal component (NLPC) computed with a neural ...
Nowcasting Foehn Wind Events Using the AdaBoost Machine Learning Algorithm
Publisher: American Meteorological Society
Abstract: he south foehn is a characteristic downslope windstorm in the valleys of the northern Alps in Europe that demands reliable forecasts because of its substantial economic and societal impacts. Traditionally, a foehn is ...
