RISPossible Change of Extratropical Cyclone Activity due to Enhanced Greenhouse Gases and Sulfate Aerosols—Study with a High-Resolution AGCM
Publisher: American Meteorological Society
Abstract: To investigate the possible impacts of enhanced greenhouse gases and sulfate aerosols on extratropical cyclone activity, two 20-yr time-slice experiments?the control run and the global warming run?are performed with a ...
Variability of the North Atlantic Cyclone Activity in Winter Analyzed from NCEP–NCAR Reanalysis Data
Publisher: American Meteorological Society
Abstract: Principal component analysis is applied to the cyclone density over the North Atlantic in winter analyzed with an objective cyclone identification and tracking algorithm by using the 6-h National Centers for Environmental ...
A Mechanism of Tropical Precipitation Change due to CO2 Increase
Publisher: American Meteorological Society
Abstract: A recent GCM study indicates that a weakening of tropical circulation associated with a slight increase in tropical precipitation may occur when atmospheric CO2 is increased. To further understand the mechanism of atmospheric ...
Interdecadal and Interannual Variability in the Northern Extratropical Circulation Simulated with the JMA Global Model. Part I: Wintertime Leading Mode
Publisher: American Meteorological Society
Abstract: Interdecadal and interannual atmospheric variability in the extratropical Northern Hemisphere is investigated using an atmospheric GCM. The model used for this research is a T42 GCM version of the Japan Meteorological ...
Interdecadal and Interannual Variations over the North Pacific Simulated by a Set of Three Climate Experiments
Publisher: American Meteorological Society
Abstract: A set of three climate experiments is performed using a T42 GCM version of the Japan Meteorological Agency global model to examine extratropical interdecadal and interannual variations over the North Pacific region associated ...
Future Changes in Structures of Extremely Intense Tropical Cyclones Using a 2-km Mesh Nonhydrostatic Model
Publisher: American Meteorological Society
Abstract: ecent studies have projected that global warming may lead to an increase in the number of extremely intense tropical cyclones. However, how global warming affects the structure of extremely intense tropical cyclones has ...
Interdecadal and Interannual Variability in the Northern Extratropical Circulation Simulated with the JMA Global Model. Part II: Summertime Leading Mode
Publisher: American Meteorological Society
Abstract: Interdecadal and interannual) variations of a model atmosphere in the northern extratropics is examined using a T42 GCM forced with observed near-global SSTs from January 1955 to December 1988. The leading mode of summertime ...
Response of Tropical Cyclone Activity and Structure to Global Warming in a High-Resolution Global Nonhydrostatic Model
Publisher: American Meteorological Society
Abstract: AbstractFuture changes in tropical cyclone (TC) activity and structure are investigated using the outputs of a 14-km mesh climate simulation. A set of 30-yr simulations was performed under present-day and warmer climate ...
Future Changes in Tropical Cyclone Activity Projected by the New High-Resolution MRI-AGCM
Publisher: American Meteorological Society
Abstract: ew versions of the high-resolution 20- and 60-km-mesh Meteorological Research Institute (MRI) atmospheric general circulation models (MRI-AGCM version 3.2) have been developed and used to investigate potential future changes ...
