Hurricanes are mixed-phase clouds, meaning that liquid and solid water (ice) are both present in the cloud. Typically, liquid water dominates at altitudes lower than the freezing level and solid water at altitudes where the temperature is colder than -40 °C. Between 0 °C and -40 °C water can exists in both phases simultaneously.
Since 1980, tropical cyclones, a generic term for hurricanes and tropical storms, have cost communities $1.4 trillion in damages and claimed more than 7,200 lives, according to The National Center ...
For example, it is estimated that flood heights from Hurricane Katrina in 2005 - one of America's deadliest storms - were 15-60% higher than they would have been in the climate conditions of 1900.
A tropical cyclone may be viewed as a heat engine that converts input heat energy from the surface into mechanical energy that can be used to do mechanical work against surface friction. At equilibrium, the rate of net energy production in the system must equal the rate of energy loss due to frictional dissipation at the surface, i.e.
The tendency for strong tropical cyclones to have undergone rapid intensification and the infrequency with which storms gradually strengthen to strong intensities leads to a bimodal distribution in global tropical cyclone intensities, with weaker and stronger tropical cyclones being more commonplace than tropical cyclones of intermediate ...
La Niña is coming, and depending on the area, it could mean heavy storms like hurricanes, typhoons, and cyclones.. The National Weather Service’s Climate Prediction Center suggests a 49% chance ...
Rapidly intensifying cyclones are hard to forecast and therefore pose additional risk to coastal communities. [7] Warmer air can hold more water vapor: the theoretical maximum water vapor content is given by the Clausius–Clapeyron relation, which yields ≈7% increase in water vapor in the atmosphere per 1 °C (1.8 °F) warming.
hurricane or typhoon — A warm-core tropical cyclone in which the minimum sustained surface wind is 74 mph or more. Hurricanes are spawned in the North Atlantic and central and eastern North Pacific Ocean. Typhoons develop in the northwest Pacific. They are known as cyclones in the Indian Ocean and the South Pacific.
