RISBarotropic Aspects of ITCZ Breakdown
Publisher: American Meteorological Society
Abstract: In satellite images the ITCZ (intertropical convergence zone) is sometimes observed to undulate and break down into a series of tropical disturbances. Tropical cyclones may later develop within these disturbances and move ...
The Role of Tropical Cyclones in the Formation of Tropical Upper-Tropospheric Troughs
Publisher: American Meteorological Society
Abstract: Tropical upper-tropospheric troughs (TUTTs), also known as midoceanic troughs, are elongated troughs that appear in summer monthly averaged maps of the upper-tropospheric flow over the oceans. The transient part of these ...
Dynamical Aspects of Twin Tropical Cyclones Associated with the Madden–Julian Oscillation
Publisher: American Meteorological Society
Abstract: A nonlinear shallow-water model on the sphere is used to study barotropic aspects of the formation of twin tropical disturbances by Madden?Julian oscillation (MJO) convection. In the model, the effect of MJO convection ...
A Climatology of the Structure, Evolution, and Propagation of Midlatitude Cyclones in the Southeast United States
Publisher: American Meteorological Society
Abstract: he seasonal and interannual variability of the structure, evolution, and propagation of midlatitude cyclones in the southeast United States are studied using a composite analysis. In the upper levels, the composites show ...
Variability of South American Convective Cloud Systems and Tropospheric Circulation during January–March 1998 and 1999
Publisher: American Meteorological Society
Abstract: A comparison of the submonthly variability of atmospheric circulation and organization of convection in South America during January?February?March of 1998 (JFM98) and January?February?March of 1999 (JFM99) is presented. ...
