Tropical cyclones begin as disturbances in the air over warm ocean waters. A tropical storm develops once the wind speed reaches 39 miles (63 kilometers) per hour. If winds blow faster than 74 miles (119 kilometers) per hour, the tropical storm becomes a cyclone. From above, a tropical cyclone looks like a huge disk of clouds. The disk can be ...

They’re called hurricanes if they occur in the Atlantic Ocean, Caribbean Sea, Gulf of Mexico, and eastern Pacific Ocean. In the western Pacific Ocean, they’re known as typhoons; in the southern Pacific and Indian Oceans, they’re called cyclones. Scientists know them all as tropical cyclones. As many as 150 occur around the world each year.

Kids learn about hurricanes (Tropical Cyclones) including how they form, names, eye, eye wall, rainbands, locations, seasons, facts, ... Tropical cyclones are categorized according to the speed of sustained winds. Tropical Depression - 38 mph or less; Tropical Storm - …

2024年7月13日 · Learn Cyclone facts for kids. Because of the Coriolis effect, the wind flow around a large cyclone is counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.In the Northern Hemisphere, the fastest winds relative to the surface of the Earth therefore occur on the eastern side of a northward-moving cyclone and on the northern side of a westward-moving one; the ...

2024年7月13日 · A hurricane or typhoon or a cyclone is a large cyclonic weather system with continuing winds of at least 33 m/s (64 kt, 74 mph, or 118 km/h). A tropical cyclone with this wind speed usually develops an eye, which is an area of calm conditions at the center of its circulation. The eye is often seen from space as a small, round, cloud-free spot.

2018年4月23日 · Cyclone Fast Facts: Where They Occur. Tropical cyclones require ocean temperatures of about 80 degrees Fahrenheit or more to form, so they arise in a fairly narrow belt on either side of the equator: mainly between 5 and 30 degrees of latitude. In the South Pacific and Indian oceans, meteorologists simply call tropical cyclones "cyclones."

A category 1 cyclone is weak and has a speed of 74-95 mph. A category 5 cyclone is above 155 mph and is extremely disastrous and dangerous. Polar Cyclones and Mesocyclones. Other types of cyclones are Polar cyclones and mesocyclone. Polar cyclones occur in Polar Regions in winter months in Greenland, Siberia or Antarctica.

2025年4月6日 · Cyclone facts. In meteorology, a cyclone refers to any low pressure area with winds spiraling inwards. Cyclones rotate clockwise in the Southern Hemisphere and anti-clockwise in the Northern Hemisphere. A cyclone is the general term for a variety of low pressure system types, such as tropical cyclones, extra tropical cyclones and tornadoes.

2025年3月22日 · Severe weather events like cyclones can be frightening for young children. However, with the right support, children can learn to feel safe and prepared. That’s why I’ve created a free short story, "The Big Blow and the Brave Town," to help children aged 5–8 understand cyclones in a positive and reassuring way.

Tropical cyclone facts. A tropical cyclone is a circular air movement that starts over the warm ocean waters in the warm part of Earth near the Equator. Most tropical cyclones create fast winds and heavy rain. While some tropical cyclones stay out in the sea, others pass over land. They can be dangerous because of flooding and because the winds pick up objects, including things as …
