RISWhy Do Similar Patterns of Tropical Convection Yield Extratropical Circulation Anomalies of Opposite Sign?
Publisher: American Meteorological Society
Abstract: ropical precipitation anomalies associated with El Niño and Madden?Julian oscillation (MJO) phase 1 (La Niña and MJO phase 5) are characterized by a tripole, with positive (negative) centers over the Indian Ocean and central ...
The Impact of the Initial Flow on the Extratropical Response to Madden–Julian Oscillation Convective Heating
Publisher: American Meteorological Society
Abstract: he response to the Madden?Julian oscillation (MJO) over the Pacific?North American (PNA) region is investigated. In addition, the sensitivity of this response to the interaction between Madden?Julian oscillation forcing ...
Testing the Sensitivity of the Extratropical Response to the Location, Amplitude, and Propagation Speed of Tropical Convection
Publisher: American Meteorological Society
Abstract: AbstractThe dynamical core of a dry global model is used to investigate the role of central Pacific versus warm pool tropical convection on the extratropical response over the North Pacific and North America. A series of ...
Can ENSO-Like Convection Force an ENSO-Like Extratropical Response on Subseasonal Time Scales?
Publisher: American Meteorological Society
Abstract: AbstractA daily El Niño?Southern Oscillation (ENSO) index is developed based on precipitation rate and is used to investigate subseasonal time-scale extratropical circulation anomalies associated with ENSO-like convective ...
