In meteorology, an invest (short for "investigative area") [1] is a designated area of disturbed weather that is being monitored for potential tropical cyclone development. Invests are designated by three separate United States forecast centers: the National Hurricane Center, the Central Pacific Hurricane Center, and the Joint Typhoon Warning ...
Common developmental patterns seen during tropical cyclone development, and their Dvorak-assigned intensities. The Dvorak technique (developed between 1969 and 1984 by Vernon Dvorak) is a widely used system to estimate tropical cyclone intensity (which includes tropical depression, tropical storm, and hurricane/typhoon/intense tropical cyclone intensities) based solely on visible and infrared ...
An accurate track forecast is essential to creating accurate intensity forecasts, particularly in an area with large islands such as the western north Pacific and the Caribbean Sea, as proximity to land is an inhibiting factor to developing tropical cyclones. A strong hurricane/typhoon/cyclone can weaken if an outer eye wall forms (typically ...
And when sustained winds of 74 miles an hour are reached, the storm has intensified, or “matured,” to the point where we now refer to it as a hurricane, a typhoon, or an intensified tropical ...
And using the right ones at the right time can be the difference between alerting of a far-out rotating storm system to a nearer full-blown hurricane. When the term “tropical cyclone” is used ...
cyclone — A storm with strong winds rotating about a moving center of low atmospheric pressure. The word is sometimes used in the United States to mean tornado and in the Indian Ocean area to mean a tropical cyclone, like a hurricane. derecho — A widespread and usually fast-moving straight-line windstorm. It is usually more than hundreds of ...
The storm made landfall in Terrebonne Parish, about 30 miles south-southwest of Morgan City, a little before 6 p.m. Eastern Time Wednesday, the National Hurricane Center said.
The NHC official forecast is light blue, while the storm's actual track is the white line over Florida. The Automated Tropical Cyclone Forecasting System (ATCF) is a piece of software originally developed to run on a personal computer for the Joint Typhoon Warning Center (JTWC) in 1988, [1] and the National Hurricane Center (NHC) in 1990.
