چکیده

Tropical cyclones, which generate storm surges, wind waves, and flooding at landfall, are a major threat to human life and property in coastal regions throughout the world. The Unit‐ ed States, the northern Gulf of Mexico, and in particular the Louisiana Gulf coast, are very susceptible to the impacts of frequent tropical storms and hurricanes due to its tropical/ subtropical location and unique bathymetric, geometric, and landscape features. Severe coastal flooding, enormous property damage, and loss of life are ubiquitously associated with tropical cyclone landfalls, and this devastation was no more evident than during Hur‐ ricanes Katrina and Rita in 2005, and Gustav and Ike in 2008. Over 1800 people lost their lives and several major coastal populations were crippled for months after the hurricanes passed. It is critically important to make timely and accurate forecasts of hurricane winds, surge, and waves. The prediction of hurricane surface winds is of specific importance be‐ cause it directly forces storm surge and wave models, and controls their forecast accuracy.

Using Proxy Records to Document Gulf of Mexico Tropical Cyclones from 1820-1915

Observations of pre-1950 tropical cyclones are sparse due to observational limitations; therefore, the hurricane database HURDAT2 (1851-present) maintained by the National Oceanic and Atmospheric Administration may be incomplete. Here we provide additional documentation for HURDAT2 from historical United States Army fort records (1820-1915) and other archived documents for 28 landfalling tropic...

Environmental Modeling, Technology, and Communication for Land Falling Tropical Cyclone/Hurricane Prediction

Katrina (a tropical cyclone/hurricane) began to strengthen reaching a Category 5 storm on 28th August, 2005 and its winds reached peak intensity of 175 mph and pressure levels as low as 902 mb. Katrina eventually weakened to a category 3 storm and made a landfall in Plaquemines Parish, Louisiana, Gulf of Mexico, south of Buras on 29th August 2005. We investigate the time series intensity change...

Tropical 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...

Upper Ocean Response to Tropical Cyclone Wind Asymmetries

The most apparent effect of a tropical cyclone on the upper ocean is the marked cooling of sea surface temperature (SST) that is clearly seen in Advanced Very High Resolution Radiometer (AVHRR) images of SST. As a storm intensifies, the increasing wind speed may increase evaporation and supply the storm with the necessary source of heat for further intensification. However, the significant SST ...

Validation of Parametric Hurricane Models by ENVISAT ASAR Images

In the past decade several satellite borne synthetic aperture radars (SAR) have been put into orbit. A synthetic aperture radar (SAR) not only records the intensity of the returned signal, but also the phase history of the backscattered radar signal and is processed to high spatial resolution images. To observe the structure of tropical cyclones at the sea surface ENVISAT ASAR and RADASAT 1 Sca...
