Observational Analysis of Tropical Cyclone Formation. Part III: Budget Analysis
Publisher: American Meteorological Society
Abstract: Vertically integrated budgets of moisture, heat, angular momentum and kinetic energy are calculated from the composite data sets of Part I (McBride, 1981). The transition from cloud cluster to typhoon/hurricane is characterized ...
Observational Analysis of Tropical Cyclone Formation. Part I: Basic Description of Data Sets
Publisher: American Meteorological Society
Abstract: Twelve composite data sets are constructed from rawinsonde data in the tropical northwest Pacific and tropical northwest Atlantic Oceans. Each data set is a composite average of approximately 80 individual disturbances. ...
Tropical-Cyclone Forecasting: A Worldwide Summary of Techniques and Verification Statistics
Publisher: American Meteorological Society
Abstract: Questionnaire replies from forecasters in 16 tropical-cyclone warming centers are summarized to provide an overview of the current state of the science in tropical-cyclone analysis and forecasting. Information is tabulated ...
The Physical Mechanism of CISK and the Free-Ride Balance
Publisher: American Meteorological Society
Abstract: The properties of the ?free-ride? assumption of balance between diabatic heating and adiabatic cooling are investigated by incorporating it into the classical two-level CISK (Conditional Instability of the Second Kind) ...
The Vertical Distribution of Heating in AMEX and GATE Cloud Clusters
Publisher: American Meteorological Society
Abstract: Tropical cloud clusters that occurred during the Australian Monsoon Experiment (AMEX) are composited and compared to a composite of the GARP Atlantic Tropical Experiment (GATE) systems. The analysis focuses on the evolution ...
Large-Scale Convective Instability Revisited
Publisher: American Meteorological Society
Abstract: Linear convective instability is revisited to demonstrate the structurally different growth rates of disturbances in balanced and unbalanced models where diabatic heating is parameterized to be proportional to the vertical ...
An Aquaplanet Monsoon
Publisher: American Meteorological Society
Abstract: A hypothesis is proposed that the seasonal evolution of sea surface temperature (SST) is the major forcing to control both the onset and the life cycle of the monsoon. A sensitive coupling of surface heat flux and cumulus ...
Observational Analysis of Tropical Cyclone Formation. Part II: Comparison of Non-Developing versus Developing Systems
Publisher: American Meteorological Society
Abstract: The thermodynamic and dynamic fields surrounding the composite tropical weather systems described in Part I (McBride, 1981a) are examined for differences between non-developing and developing systems. The main findings are ...
Sea Surface Temperature Response to Tropical Cyclones
Publisher: American Meteorological Society
Abstract: he response of sea surface temperature (SST) to tropical cyclones is studied using gridded SST data and global cyclone tracks from the period 1981?2008. A compositing approach is used whereby temperature time series before ...
The Threshold Sea Surface Temperature Condition for Tropical Cyclogenesis
Publisher: American Meteorological Society
Abstract: he analyzed value of sea surface temperature (SST) is examined for all global cases of tropical cyclone formation within 35° latitude of the equator over the period 1981?2008. It is found that 98.3% of formations occur at ...
