Hurricanes, cyclones, thunderstorms and tornadoes fall under the different types of weather disturbances. These are some of the most frequently occurring weather disturbances throughout the world. They are also referred to as natural disasters, as they are capable of wreaking havoc on roads, power lines and buildings.
Tropical cyclones are classified as tropical storms, tropical depressions and typhoons. When a tropical cyclone occurs in the part of the Northwest Pacific Ocean that is west of the dateline and reaches wind speeds of at least 74 mph, it is called a typhoon. If a tropical cyclone of that intensity occurs in the North Atlantic, in the Northeast Pacific east of the dateline or the South Pacific east of the 160th meridian east, it is called a hurricane.
In some cases, weather disturbances may cause severe weather conditions. Tropical cyclones tend to produce strong winds and heavy rainfall that may lead to flash flooding. Thunderstorms, which kill more people than hurricanes and tornadoes, produce thunder, lightning and sometimes hail. Violent storms such as tornadoes and hurricanes are equally destructive.Learn more about Storms
While tropical cyclones are not unheard of in South Africa, they are very rare. However, according to a study by the Wits School of Geography, Archaeology and Environmental Studies, the number of cyclones that strike South Africa may steadily increase in response to increased global warming.Full Answer >
Stormy weather is associated with heavy rain, hurricanes, tornadoes, typhoons, hail, sleet, tropical cyclones and general thunderstorms. Atmospheric instability is one of the causes of stormy weather, as well as high pressure zones moving in from certain directions. For example, a high pressure zone from the north causes colder weather as winter approaches and a high pressure zone from the south brings warm weather.Full Answer >
A clipper system is a fast-moving, low-pressure system sliding along a track that separates cold air to the north and northeast from warmer air in the south and southwest. Clippers can lower temperatures by as much as 30 degrees Fahrenheit in 12 hours or less.Full Answer >
Types of storms include blizzards, hail storms, heavy rain storms, ice storms, lightning storms and thunderstorms. Each type of storm requires a certain level of preparation to keep people and animals safe and minimize damage to structures.Full Answer >
