Many of the times you read in the newspaper or watch the news on television talking about the storms, reporters and the government ask the public to stay home for safety purposes. Ever thought about why they asked us to stay inside? Don’t worry if you are not aware of the answers. Vedantu has brought detailed notes on the storms to help students understand the topic in detail.
A storm is the disturbance caused in the atmosphere when the ocean develops a low-pressure zone. It brings heavy rain and destruction to the coastal areas. But, for the drought-affected areas, it is a blessing in disguise.
In the notes, Vedantu has also explained the different types of storms, for instance, tornadoes, hail storms, and many more.

Since the past decade, storm occurrence has become very frequent and has already taken a lot of lives. Today is the right time for students to learn about it and the reasons for the occurrence of the storms.
Storms are nothing but strong and gusty winds accompanied by snowfall or heavy rain. A wind that you may know as the air; feels so pleasant in the heat of summer, but it shows its ghostly powers as a storm that can even collapse the high storey buildings.
Do you know what wind is?
The wind is the moving air that flows from a high-pressure area to a low-pressure area within the atmosphere. Strong winds can uproot trees, roofs of skyscrapers, and several other things it can do.
The wind is essential for human existence on the earth. It is the means of carrying monsoon clouds from one place to another, bringing rain to the locations away from the water bodies. It also helps in the process of sheet erosion. Wind increases the availability of carbon dioxide to plants to carry out the process of photosynthesis. But, often, the wind brings severe destruction. In this section, students will learn about the reasons that cause storms.
What causes storms?
The short answer to this question is storms need the following things: moisture, unstable air, and lift. The ocean is the sole source of moisture content. When warm moist air is near the ground and cold, dry air is above unstable air is formed. Density is the reason that lifts the air as it pushes unstable air upward, which creates storm clouds. The most dangerous stage of storms is when flooding, hail storms start to happen. Moist and warm air continuously fills the storm until it reaches a landscape where the moisture content is low or zero.

More About Storm
The storm is an acute disturbance of the atmosphere which is coupled by the mighty wind and usually by heavy or light rain, snow, hail, sleet, or thunder and accompanied by lightning. During a storm, the wind has a speed of 64 to 72 miles (which is 103 to 117 kilometers) per hour.
A storm is identified as a violent meteorological phenomenon where there is an occurrence of heavy rain and gusty strong winds. In our further section, we will know more about Storms, a common occurrence in our life.
Storms are the raging atmospheric disturbance that is characterized by cloud cover, low barometric pressure, precipitation, and also with wild winds. They are also coupled with thunder and lightning.
The cause of the storm is the moisture content in the air. The Formation of Hail and Lightning are also quite common encounters with the storms. A storm generally happens in bad weather and accompanied by strong winds, thunder, lightning, and also heavy precipitation like ice.
The storm is a general term, which is popularly used to describe other disturbing varieties of atmospheric disturbances, that ranges from ordinary rain showers and snowstorms to the happening of thunderstorms, wind-related disturbances, and gusts of wind like gales, tornadoes, sandstorms, tropical cyclones.
Meteorologically, the storm is restricted to a cyclone that has a strong low-pressure center, strong winds that range from 103–117 kilometers per hour (which is 64–73 miles per hour), heavy precipitation, and also lightning and thunder.
Strom is the type of disturbance in the atmosphere which is manifested by gusty and strong winds which are accompanied by rain, snow, or other precipitation and are often struck by thunder and lightning.
A storm is described as a disturbed state in the environment or in the atmosphere which affects the surface, and this implies severe weather conditions. This is also marked by significant disruptions to normal conditions such as strong winds, tornadoes, hail, thunder, and also lightning with heavy precipitation which is known as a snowstorm, rainstorm with heavy rain like the ice storm, the storm is freezing as well. The tropical cyclone and windstorm or the wind transporting substances via the atmosphere as in the case of a dust storm, blizzard, sandstorm, etc.
These strong, gusty storms have the potential to harm the lives and property of human beings. Also, for this it causes rain or snow causing flood or road passing incapability, lightning and wildfires may also happen, and also causes of wind shear are witnessed.
Storms with heavy rainfall and duration relieve the drought areas. The heavy snowfall also might allow other recreational activities like skiing and snowmobiling.
Storms are then created when a center of low pressure gets developed with the high-pressure system that surrounds it. These opposing forces can also create winds which result in the formation of the storm clouds like cumulonimbus. The localised areas of low pressure can also form from hot air rising off from the hot ground, which results in smaller disturbances like dust devils and whirlwinds.
Types of Storms
Now that we have covered what is storm, let us now learn about the different types of storms are as follows:
1. Deroche Storms
Deroche storms are the series of storms that have a large extent they all;l follow the path of each other even which at least 240 miles with wind gusts of at least 58mph.
Floods also occur due to the rain and while other water rising faster than the drains can handle. Flooding often leads to high damage to homes and other commercial buildings.
3. Hail Storms
Hail storms are the cause of a lot of damage which is hard and can fall up to high speeds of up to 120mph.
4. Snow Storms
Heavy snow may also be an inconvenience that can cause damage to the home, heavy build-ups of snow can also lead to collapsing of roofs, or gutters. It also causes blockage of drains.
The hurricane is the most powerful and dangerous type of tropical cyclone, they are identified by low-pressure systems, high winds, heavy rainfall, and storm surges and swells.
6. Ice Storms
Ice storms produce freezing rain that covers everything in ice, they make everything slippery and also cause hazardous conditions and a high potential of affecting homes and vehicles.
Lightning happens for storm damage, and this usually causes trees to fall, wildfires, structural fires, and also power outages.
Thunderstorms cause a wide range of types of weather, like hail, flooding, and tornadoes.
Tornadoes are very dangerous, as the high winds often gush in excess of 300mph. Tornadoes are very much prevalent in certain states like Oklahoma, Kansas, Texas, and Missouri. They are named “tornado alley”. Minnesota, which lies on the northern edge, witnesses around 26 tornadoes per year, with an average of more than 2 per month.
10. Tropical Storms
Tropical storms have wind speeds of between 39 to 73mph, they are prevalent in the Pacific and Atlantic oceans.
The main damage is caused by tropical storms which include damage that happens to the water.
