The Observations Of Hurricane Katrina - 1049 Words

Abstract The observations of Hurricane Katrina are examined by several data assimilations and forecast experiments from the Geostationary Operational Environment Satellite (GOES) rapid-scan (RS) wind observations. The satellites tracks cloud motions from a five minute images and intervals. During the observations, operational forecast are supplemented, with the inclusion that errors are reduced in Katrina landfall positions. From the eighty-four to one hundred and twenty hour marks that the large averages of improvements are made in Katrina’s track forecast. The RS wind observations can be used to improve the track forecast of hurricanes. Introduction Weather predictions continued to be a challenge when improving the forecast of tropical cyclones, also known as a hurricane (TC). Today, the TC track for forecasts have largely improved due to the amount of quality of observations, improved forecast models, and data assimilation procedures. To improve analysis and forecast events, methods to identify sensitive locations of the atmosphere have to be specially observed. Special observations are intended to improve initial conditions and merge forecasts products. The most common approach used in targeted observing is for an aircraft to deploy sets of ten to forty dropsondes in the targeted regions. Satellite- derived observations are also a targeted mode to improve forecast. Advantages when using satellite observations are large numbers of observations, observe wide andShow MoreRelatedRemote Sensing And Weather Patterns Essay1390 Words   |  6 Pages The use of remote sensing to observe weather patterns especially hurricanes and their aftermath have only been widely used in the last fifty years. Early hurricane observations were made from ships or on land up until the 1960s (Hodgson, Davis, Cheng, Miller, 2013, p. 9). During that decade, the first United States satellite capable of producing images, the Television Infrared Observation Satellite (TIROS), was launched into space (Hodgson et. al, 2013, p. 9). This allowed for meteorologists toRead MoreClassical Principles or Argument Essay1169 Words   |  5 Pagesaccumulation of mutually su pporting points† (Lamm, p. 79).It adheres to an individual’s capability to be able to write syntheses relies on your ability to derive a relationship amid your sources like writing documents, such as, lectures, essays or even observations.

One neighborhood that faced massive damage from hurricanes (such as Katrina and Sandy) is the Bowery. Even to this day, the Bowery is still disheveled. There is trash on the streets, people are sleeping on the sidewalk, and rain pools in the streets and the subway. These factors slowed Bowery’s recovery rate from natural disasters. Financial devastation and maintenance issues, combined with the damage of heavyRead MoreThe American Red Cross Is A Humanitarian Based Organization Created By Clara Barton1566 Words   |  7 PagesThe Red Cross is a large operating organization that attends to the U.S population and with the situation going on at New York at the time you would believe there would be some type of monitoring.
