What is tropical storm in simple words?
: a tropical cyclone with strong winds of over 39 miles (63 kilometers) per hour but less than hurricane intensity.
How would you describe a tropical storm?
A tropical storm is a very powerful low-pressure weather system. It has strong winds and heavy rainfall that can be disruptive and dangerous. They all develop in the same way, have the same characteristics and are all tropical storms.
How do tropical storms form for kids?
Hurricanes form over the warm ocean water of the tropics. When warm moist air over the water rises, it is replaced by cooler air. The cooler air will then warm and start to rise. If there is enough warm water, the cycle will continue and the storm clouds and wind speeds will grow causing a hurricane to form.
What does tropical storm mean in weather?
Tropical Storm: A tropical cyclone with maximum sustained winds of 39 to 73 mph (34 to 63 knots). Hurricane: A tropical cyclone with maximum sustained winds of 74 mph (64 knots) or higher.
How does a tropical storm form?
Tropical storms usually form between 5° and 30° latitude. When the ocean surface waters reaches at least 27°C due to solar heating, the warm air above the water rises quickly, causing an area of very low pressure. As the air rises quickly more warm moist air is drawn upwards from above the ocean creating strong winds.
What causes a tropical storm?
Tropical cyclones are like giant engines that use warm, moist air as fuel. That is why they form only over warm ocean waters near the equator. The warm, moist air over the ocean rises upward from near the surface. As the warmed, moist air rises and cools off, the water in the air forms clouds.
What are characteristics of a storm?
storm, violent atmospheric disturbance, characterized by low barometric pressure, cloud cover, precipitation, strong winds, and possibly lightning and thunder.
How do you explain typhoon to a child?
A typhoon is a name for a cyclone, a big storm that forms in warm, tropical ocean waters of the world. Typhoons occur in western and northern areas of the Pacific Ocean, and are storms that rotate, or spin around a center called an eye.
Why is it called a tropical storm?
Once the surface wind speeds in a tropical depression reach 63 km (39 miles) per hour, the regional storm-warning centre assigns a name to the disturbance, and it is classified as a tropical storm. Since tropical storms are the precursors to the more intense tropical cyclones, they occur more often.
What happens during a tropical storm?
Tropical storm The winds blow faster and begin twisting and turning around the eye, or calm center, of the storm. Wind direction is counterclockwise (west to east) in the northern hemisphere and clockwise (east to west) in the southern hemisphere. This phenomenon is known as the Coriolis effect.
What is tropical storm and its development?
tropical storm, organized centre of low pressure that originates over warm tropical oceans. If local atmospheric conditions support deep convection and low vertical wind shear, the system may become organized and begin to intensify. Intensification occurs as the air warmed at the surface begins to rise.
What are the effects of a tropical storm?
The immediate effects of strong winds, high rainfall and storm surges . Buildings and bridges can be destroyed, people can get into difficulties in the water, and roads and railways can become damaged. Power cables and telephone lines come down, crops are ruined, and water and sewage supplies are affected.
What are the categories of tropical storm?
Generally, there are three main category names of tropical storms. Cyclones. These happen around the Indian Ocean and the South-East Pacific. Cyclones tend to appear in countries like Madagascar, India, and parts of Australia. They also often attack countries like Japan, and Indonesia, Malaysia, and nearby countries.
What are the criteria for a tropical storm?
Meteorologists then use the following labels to classify the cyclone: Tropical Depression: a tropical cyclone with maximum sustained wind speeds less than 34 knots (39 miles per hour). Tropical Storm: a tropical cyclone with maximum sustained wind speeds of at least 34 knots (39 miles per hour). Hurricane: a tropical cyclone with maximum sustained winds of at least 64 knots (74 miles per hour).
What is the difference between a hurricane and a tropical depression?
Hurricanes and tropical storms are both very large storms. They are both of a tropical nature, and the difference between them lies in the speed of the wind. Hurricanes and tropical storms start as a tropical depression. Tropical depressions start as a low pressure area over the ocean which has the potential to get larger and stronger.
What is the wind force of a tropical storm?
A tropical storm is a tropical cyclone with maximum sustained winds of at least 34 knots (39 mph or 63 kph).
