Tropical cyclones can affect the Federated States of Micronesia any time of year. Storms cause about US$8 million in damage or losses each year, equivalent to 2.8% of the country's GDP. The nation's costliest storm on record was Typhoon Mitag in 2002, which left US$150 million in damage or losses, along with one fatality. [187]
The exports and imports are halted in sea ports due to the cyclone. Some people lose their jobs as well. A mature tropical cyclone can release heat at a rate upwards of 6×10 14 watts. [1] Tropical cyclones on the open sea cause large waves, heavy rain, and high winds, disrupting international shipping and, at times, causing shipwrecks. [2]
Extratropical cyclones can also be dangerous when their low-pressure centers cause powerful winds and high seas. [120] A subtropical cyclone is a weather system that has some characteristics of a tropical cyclone and some characteristics of an extratropical cyclone. They can form in a wide band of latitudes, from the equator to 50°.
[10] [11] Cyclones can transition between extratropical, subtropical, and tropical phases. [12] Mesocyclones form as warm core cyclones over land, and can lead to tornado formation. [13] Waterspouts can also form from mesocyclones, but more often develop from environments of high instability and low vertical wind shear. [14]
Tropical cyclone forecast model – computer program that uses meteorological data to forecast tropical cyclones and their potential impact. Tropical cyclone forecasting – the science of forecasting a tropical cyclone's strength, intensity, and potential effects in land areas.
Until the start of the 1985–86 tropical cyclone season the basin only extended to 80°E, with the 10 degrees between 80 and 90E considered to be a part of the Australian region. [31] On average about 9 cyclones per year develop into tropical storms, while 5 of those go on to become tropical cyclones that are equivalent to a hurricane or a ...
That’s not to say tropical storms can’t form in the northeast Pacific every now and then. In 1975, a nameless hurricane formed from the remnants of Hurricane Ilsa northeast of Hawaii.
The Philippines is a Typhoon (Tropical Cyclone)-prone country, with approximately 20 Tropical Cyclones entering its area of responsibility per year. Locally known generally as bagyo (), [3] typhoons regularly form in the Philippine Sea and less regularly, in the South China Sea, with the months of June to September being the most active, August being the month with the most activity.
