Hurricane Dean was the strongest tropical cyclone of the 2007 Atlantic hurricane season. National forecast for Friday, July 31: Tracking Hurricane Isaias. Ad Stoffelen of the Royal Netherlands Meteorological Institute (KNMI), which processes ESA’s scatterometer images, said: "Observed winds from hurricane Dean by ESA's ERS-2 scatterometer are provided to meteorologists within the hour.

Dean was upgraded early Tuesday to a Category 5, the highest on the Saffir-Simpson scale, before pummelling the peninsula. Scatterometer results enable measurements of not only wind speed but also direction across the water surface. The storm largely spared South …

ESA satellites are tracking the path of Hurricane Dean as it rips across the Caribbean Sea carrying winds as high as 260 km/h. 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. 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.

Cuba's Civil Defense evacuated 350,000 people from the coastal provinces.With Hurricane Dean's path predicted well in advance of the storm,A hurricane warning was issued for the coastal locations north of The United Nations Disaster Assessment and Coordination team dispatched two members to Belize City and the rest of the team traveled to Belmopan.Throughout the Caribbean Sea, about a dozen cruise ships altered their routes to avoid Hurricane Dean.Fifteen countries felt the effects of Hurricane Dean as its path through the Caribbean Sea claimed 42 lives. What makes ERS-2's scatterometer especially valuable is that its C-band radar frequency is almost unaffected by heavy rain, so it can return useful wind data even from the heart of the fiercest storms. 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. Quit! 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. Water temperatures are the main underlying energy reservoir that power hurricanes; together with the correct atmospheric conditions, temperatures need to exceed 26ºC in order to form and maintain a tropical cyclone. Flat Random Noise. Martinique experienced 75 mph (120 km/h) winds with gusts to 105 mph (170 km/h).On the evening of August 16, 12 hours before the storm arrived in St. Lucia, power outages began in some of the island's neighborhoods.

Warm waters may extend to at least 100 meters beneath the surface in many of these oceanic features, representing waters of very high heat content. The book is an account of surfing America's hurricane states and the swell produced by Hurricane Dean.This article is about the Atlantic hurricane of 2007. Stop. 5,000 acres (20 kmThe storm passed to the south of most of the Greater Antilles, though its outer rain bands crossed many of the islands, and delivered hurricane-force winds to Jamaica. August 21, 2007

Although the wave initially experienced strong easterly wind shear, it quickly moved into an environment better suited for tropical development and gained organization. Apart from any fair dealing for the purpose of private study or research, no Get weekly and/or daily updates delivered to your inbox. The expectation is that Dean will be close to the Lesser Antilles in 5 days. The hurricane, which has already claimed eight lives, is forecast to slam into Mexico’s Yucatan Peninsula on Tuesday morning.
