We do not guarantee individual replies due to extremely high volume of correspondence. The scatterometer instrument works by firing a trio of high-frequency radar beams down to the ocean, then analysing the pattern of backscatter reflected up again. ESA satellites are tracking the path of Hurricane Dean as it rips across the Caribbean Sea carrying winds as high as 260 km/h. Several hurricanes have intensified when their tracks pass over eddies or other masses of warm water with high TCHP values.The US National Oceanic and Atmospheric Administration (NOAA) is using Envisat RA-2 results along with those from other space-borne altimeters to chart TCHP and improve the accuracy of hurricane forecasting.Envisat's Advanced Along Track Scanning Radiometer (AATSR) works like a space-based thermometer, acquiring the temperature of the sea surface down to a fraction of a degree.
The hurricane, which has already claimed eight lives, is forecast to slam into Mexico’s Yucatan Peninsula on Tuesday morning. The hurricane's intense winds, waves, rains and storm surge were responsible for at least 45 deaths across ten countries and caused estimated damages of US$1.66 billion. The storm largely spared South … Dean off coast of Haiti The Medium Resolution Imaging Spectrometer (MERIS) optical instrument shows the swirling cloud-tops of a hurricane, while radar instruments such as the Advanced Synthetic Aperture Radar (ASAR) pierce through the clouds to show how the wind fields shape the sea surface and estimate their likely destructive extent. Because warm water expands, scientists can locate warm underwater ocean features by detecting bulges in the ocean surface height, as detected by RA-2.The thermal energy of warm water, which partly powers a hurricane, is known as tropical cyclone heat potential (TCHP). Tropical Storm Isaias remained well off the Florida coast on Sunday evening, and was headed toward the Carolinas. Wind-driven ripples on the ocean surface modify the radar backscatter, and as the energy in these ripples increases with wind velocity, backscatter increases as well. The hurricane, which has already claimed eight lives, is forecast to slam into Mexico’s Yucatan Peninsula on Tuesday morning. "Another Envisat instrument called the Radar Altimeter-2 (RA-2) uses radar pulses to measure sea surface height (SSH) down to an accuracy of a few centimetres. Scatterometer results enable measurements of not only wind speed but also direction across the water surface. Envisat carries both optical and radar instruments, enabling researchers to observe high-atmosphere cloud structure and pressure in the visible and infrared spectrum.The Medium Resolution Imaging Spectrometer (MERIS) optical instrument shows the swirling cloud-tops of a hurricane, while radar instruments such as the Advanced Synthetic Aperture Radar (ASAR) pierce through the clouds to show how the wind fields shape the sea surface and estimate their likely destructive extent.ERS-2 uses its radar scatterometer to observe the hurricane's underlying wind fields. Reconnaissance aircraft confirmed 970 mb central pressure and 90 mph sustained winds (will probably increase soon in response to pressure drop). Hurricane Dean's smooth and well-predicted track gave unusually advance warning to all of the nations in its path and allowed them time to prepare for the storm's impact. Update #3. The meteorological history of Hurricane Dean began in the second week of August 2007 when a vigorous tropical wave moved off the west coast of Africa into the North Atlantic ocean. Additionally, it made the third most intense Atlantic hurricane landfall.

The hurricane, which has already claimed eight lives, is forecast to slam into Mexico’s Yucatan Peninsula on Tuesday morning. The Lesser Antilles and the Greater Antilles were especially quick to resume servicing cruise lines, as their ports opened within days.Although Hurricane Dean was only a Category 2 hurricane when its northern eyewall passed over Martinique, the wind and widespread flooding destroyed 70% of the island's sugar cane crop and all of its banana crop, valued at €400 million The French Overseas Minister, Christian Estrozy and French Prime Minister, Francois Fillon visited French Caribbean island to assess the storm's damage.
Because of the advance warning and Dean's extraordinary strength, the nations of Central America and the Caribbean set up hundreds of shelters, readied thousands of disaster recovery experts, evacuated hundreds of thousands of vulnerable residents, and prepared millions of dollars of emergency supplies. November 12, 2010 2007-08-16. Stop. Stop. This thing is deepening fairly quickly. Source: European Space Agency Dean is a Category 4 hurricane, and is forecasted to hit the southern Yucatan Peninsula early tomorrow morning, … ESA satellites are tracking the path of Hurricane Dean as it rips across the Caribbean Sea carrying winds as high as 260 km per hour.
Scatterometer winds are used directly by shift meteorologists in forecast rooms and to initialise Numerical Weather Prediction models aiding the forecasting of hurricanes 5 days ahead." Dean was upgraded early Tuesday to a Category 5, the highest on the Saffir-Simpson scale, before pummelling the peninsula. Get weekly and/or daily updates delivered to your inbox.
Although the wave initially experienced strong easterly wind shear, it quickly moved into an environment better suited for tropical development and gained organization. The scatterometer instrument works by firing a trio of high-frequency radar beams down to the ocean, then analysing the pattern of backscatter reflected up again. As Hurricane Isaias' heaviest bands approached North Myrtle Beach, South Carolina, Monday evening, Dean Burris watched from the balcony of his … Quit!
