Because RAINEX was planned in advance of the 2005 Atlantic Hurricane Season, it did fly in to Hurricane Katrina among other storms. Hurricane Katrina followed a very similar track to a later storm in this season (Hurricane Rita); however, Katrina did not undergo eyewall replacement during its time in the Gulf of Mexico. RAINEX flights into ...
Concentric eyewalls seen in Typhoon Haima as it travels west across the Pacific Ocean.. In meteorology, eyewall replacement cycles, also called concentric eyewall cycles, naturally occur in intense tropical cyclones with maximum sustained winds greater than 33 m/s (64 kn; 119 km/h; 74 mph), or hurricane-force, and particularly in major hurricanes of Saffir–Simpson category 3 to 5.
Rainbands in advance of warm occluded fronts and warm fronts are associated with weak upward motion, [1] and tend to be wide and stratiform in nature. [2] In an atmosphere with rich low level moisture and vertical wind shear, [3] narrow, convective rainbands known as squall lines form generally in the cyclone's warm sector, ahead of strong cold fronts associated with extratropical cyclones.

New tools from the National Hurricane Center aim to better predict storms and alert the public for hurricane season with more frequent updates to get people to prepare for dangers.
A shelf cloud, such as this one, can be a sign that a squall is imminent.. A mesoscale convective system (MCS) is a complex of thunderstorms that becomes organized on a scale larger than the individual thunderstorms but smaller than extratropical cyclones, and normally persists for several hours or more.
Waqar Ali, president of Hurricane Engineering and Testing in Doral, explains the physics behind storm-window material standards that are required in Miami-Dade County. DOUGLAS HANKS/dhanks ...
The history of tropical cyclone track forecasting has evolved from a single-station approach to a comprehensive approach which uses a variety of meteorological tools and methods to make predictions. The weather of a particular location can show signs of the approaching tropical cyclone, such as increasing swell, increasing cloudiness, falling ...
The National Hurricane Research Laboratory (NHRL) is the hurricane research arm of the National Oceanic and Atmospheric Administration. It was formed in December 1964 out of the National Hurricane Research Project , the U. S. Weather Bureau's effort to scientifically examine tropical cyclones in order to make better predictions.
