Characteristics of Trs/tropical revolving storms
a tropical storm is like a huge whirlpool - a gigantic mass of revolving moist air. Tropical storms are between 482-644 kilometres wide and 6-8 kilometres high. They move forward at speeds of 16-24 km/h, but can travel as fast as 65 km/h
Distribution of trs
As tropical storms require warm oceans, they are normally found in tropical regions between 5° and 30° north and south of the equator where the water is warmest. They usually form in the late summer when sea temperatures are at their highest.
Measurement of TRS-
he Saffir-Simpson Hurricane Wind Scale is designed to help determine wind hazards of an approaching hurricane easier for emergency officials.he Saffir-Simpson Hurricane Wind Scale consists of a five point scale of hurricane intensity and starts at 74 mph. Tropical cyclones with wind speeds up to 38 mph are classified as tropical depressions and those with wind speeds from 39 - 73 mph are classified as tropical storms.
how does a tropical cyclone happen
Warm ocean water. The ocean water must be at least 26.5 °C. …
Low pressure. A tropical cyclone starts life as a tropical low. …
Force to make it spin. As the warm, moist air rises, the developing tropical cyclone begins to spin. …
More moisture. …
Cyclone eye and eye wall. …
causes of volcanoes, including the role of plate boundaries and hotspots.
Another feature associated with volcanic activity is a hotspot, where a rising plume of hot mantle can lead to volcano formation at the surface. As the tectonic plate moves above a hotspot, a line of volcanoes may form on top of the plate.
At a convergent plate boundary, one plate dives or “subducts” beneath the other
Measurement of earthquakes
While the Mercalli scale describes the intensity of an earthquake based on its observed effects, the Richter scale which describes the earthquake’s magnitude by measuring the seismic waves.
