Mountain Torques and Intraseasonal Atmospheric Oscillations
Broad-peak intraseasonal oscillations in large-scale Northern Hemisphere atmospheric circulation patterns provide a basis for extended-range weather prediction, given an understanding of the underlying mechanisms. Theoretical work and general circulation model (GCM) experiments suggest that the midlatitude jet stream's interaction with large-scale topography can drive such oscillations through ...
متن کاملModel of intraseasonal oscillations in earth's atmosphere.
We suggest a way of rationalizing intraseasonal oscillations of Earth's atmospheric flow as four meteorologically relevant triads of interacting planetary waves, isolated from the system of all of the rest of the planetary waves. Our model is independent of the topography (mountains, etc.) and gives a natural explanation of intraseasonal oscillations in both the Northern and the Southern Hemisp...
متن کاملKernel analog forecasting of tropical intraseasonal oscillations
This paper presents the results of forecasting the Madden-Julian oscillation (MJO) and boreal summer intraseasonal oscillation (BSISO) through the use of satellite-obtained global brightness temperature data with a recently developed nonparametric empirical method. This new method, referred to as kernel analog forecasting, adopts specific indices extracted using the technique of nonlinear Lapla...
متن کاملThe skeleton of tropical intraseasonal oscillations.
The Madden-Julian oscillation (MJO) is the dominant mode of variability in the tropical atmosphere on intraseasonal timescales and planetary spatial scales. Despite the primary importance of the MJO and the decades of research progress since its original discovery, a generally accepted theory for its essential mechanisms has remained elusive. Here, we present a minimal dynamical model for the M...
متن کاملA multiscale model for tropical intraseasonal oscillations.
The tropical intraseasonal 40- to 50-day oscillation (TIO) is the dominant component of variability in the tropical atmosphere with remarkable planetary-scale circulation generated as envelopes of complex multiscale processes. A new multiscale model is developed here that clearly demonstrates the fashion in which planetary-scale circulations sharing many features in common with the observationa...
