Rosenstiel School researchers David Nolan, Brian McNoldy, James Hlywiak, and Jimmy Ge are using sophisticated supercomputer simulations to . Hurricane Laura will exceed both Katrina and Harvey in one critical metric — sustained wind speed. It is estimated that 80-90% (approximately 104-119mph) of the maximum . Yet, predicting the intensity of hurricanes is a difficult challenge. How did Hurricane Katrina develop? The maximum sustained wind speed upon first emerging over water again was 65 kt, but soon, due in large part to the warm waters of the Gulf Loop Current, it began its first period of RI. Similar results were found following Hurricane Katrina (2005); the FEMA MAT identified wind impacts to rooftop equipment as one area requiring "additional attention" from designers, architects, and contractors [FEMA 549, 2006]. Katrina had the third lowest air pressure reading ever made for hurricanes up to that point, and it became the deadliest and most destructive hurricane to hit the U.S. in 80 years. 2.2.2 Recorded and Modeled Wind Speeds, Hurricane Katrina ...13 2.2.3 Wind Speed - Hurricane Rita...18 . Winds peaked at 175 mph (280 kph) over the eastern Gulf of Mexico, with gusts to . Since it takes a reconnaissance aircraft about 6h to sample the wind field of the hurricane, it is difficult to resolve the timing of peak intensity to better than 3h about any analysis time. Copy. "z" time is an abbreviation for Zulu time - which is GMT time. Part A: Air Pressure and Wind Speed in Hurricane Katrina. Blank #1: Approximate the wind speed for a hurricane with barometric pressure of 700 mb. The top wind speeds for Hurricane Katrina were 175mph. Animations: small (2.8 MB MPEG); large (18 MB MPEG); When Hurricane Katrina moved over the Gulf Coast of the United States on August 29, 2005, its effects were felt far from the reach of its powerful winds, drenching rains, and surging surf. The wind speed is estimated, using hurricanes with similar pressure readings at landfall, because of the lack of wind instruments at the time. Hurricane Katrina was a large and destructive Category 5 Atlantic hurricane that caused over 1,800 fatalities and $125 billion in damage in late August 2005, especially in the city of New Orleans and the surrounding areas. Wind speed-damage correlation is useful especially when few ground-based wind speed measurements are available. As well as the damaging winds, Ida produced a lot of rainfall. The tropical depression strengthened, and its circular motion became more organized until it was a tropical storm with wind speeds between 39 and 73 mph. Atlantic hurricane season had 30 named storms, the most in recorded history, with two more than in 2005, which included Hurricane Katrina. Sep 4, 2005. But the Saffir-Simpson scale only goes up to 5.
