According to the World Meteorological Organization, the different weather disturbances are tropical cyclones, intense tropical cyclones, low-pressure areas, very intense tropical cyclones, tropical waves, tropical disturbances, tropical depressions, extra-tropical disturbances, subtropical disturbances, moderate tropical storms, severe tropical storms and zones of disturbed weather. A weather disturbance is a term used to describe a change in atmospheric conditions or weather patterns.Know More
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
The minimum sustained wind speed required for a tropical storm system to be classified as a hurricane is 74 mph, but tropical cyclones have been recorded with wind speeds as high as 215 mph. However, only tropical systems occurring in the Atlantic and eastern Pacific basins are called hurricanes.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 >
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 >
There are five types or categories of hurricanes, which are classified on a 1-5 rating based on wind speed. Storms are rated on their strength based on the Saffir-Simpson Hurricane Wind Scale. Small storms are classified as category 1 or 2 storms, while those identified as 3-5 on the scale are considered major storms.Full Answer >
