The Effect of Tropical Cyclone Characteristics on U.S. Landfall Probability
When a tropical cyclone threatens the coastline, decision makers can take preparatory actions designed to mitigate the damage caused by landfall. Those in this situation must decide whether and when to begin their preparations. Regnier and Harr have developed a dynamic decision model in which the decision maker has the option of delaying preparation and waiting for an updated, more accurate for...
متن کاملTropical Cyclone Intensity Change before U.S. Gulf Coast Landfall
Tropical cyclone intensity change remains a forecasting challenge with important implications for such vulnerable areas as the U.S. coast along the Gulf of Mexico. Analysis of 1979–2008 Gulf tropical cyclones during their final two days before U.S. landfall identifies patterns of behavior that are of interest to operational forecasters and researchers. Tropical storms and depressions strengthen...
متن کاملTropical Cyclone Intensity and Structure Changes in relation to Tropical Cyclone Outflow
The overarching objective of this project is to identify impacts to tropical cyclone structure and intensity throughout the tropical cyclone lifetime. A common factor is the impact of midand upperlevel environmental conditions that affects formation and intensification of a tropical cyclone. It is hypothesized that during the formation process, the environmental interaction has maximum impact o...
متن کاملPotential Vorticity Diagnosis of a Tropopause Polar Cyclone
Long-lived coherent vortices located near the tropopause are often found over polar regions. Although these vortices are a commonly observed feature of the Arctic, and can have lifetimes longer than one month, little is known about the mechanisms that control their evolution. This paper examines mechanisms of intensity change for a cyclonic tropopause polar vortex (TPV) using an Ertel potential...
متن کاملInterdecadal variability of tropical cyclone landfall in the Philippines from 1902 to 2005
[1] A dataset of tropical cyclone landfall numbers in the Philippines (TLP) is created from a combination of historical observation records of the Monthly Bulletins of Philippine Weather Bureau and Joint Warning Typhoon Center best-track data for the period of 1902 to 2005. Interdecadal variability of TLP is found to be related to different phases of the El Niño/Southern Oscillation (ENSO) and ...
