How do storms form?

Answer 1

The action of warm air rising and cold air sinking (convection) plays a key role in the formation of severe thunderstorms. If the warm surface air is forced to rise, it will continue to rise, because it is less dense than the surrounding air. In addition, it will transfer heat from the land surface to upper levels of the atmosphere through the process of convection.

Answer 2

Storms start as an imbalance in the magnetic field that

creates the physical manifestations (tornadoes, hurricanes,

lightning, etc.) that are attempts to regain balance. (I do not take credit for these findings, i am only filling you in on the right answer)

Answer 3

The generic name tropical storm is applied to typhoons, cyclones and hurricanes. These storms form over tropical waters in the Atlantic, Pacific and Indian Oceans.

In order for a tropical storm to form several different factors must come together. The water must be over 28C (80F) and deep enough to provide the energy needed to power the storm. The depth required is unknown but the warmer the water the less the depth that is required as more energy is held in the water: the minimum depth required appears to be fifty metres.

The storm season is towards the end of summer and start of autumn when the ocean waters are warmest but the air is beginning to cool. For a storm to form the air over the sea must cool quickly allowing heat to be rapidly released into the air along with moisture. The moist air rises more quickly than it can be replaced from below, creating an area of low pressure. If the mid-troposphere i also moist (five kilometres above the earth) a column of warm moist air is formed. Air moves towards the area of low pressure to fill it.

A storm will not form even now unless certain other conditions are met. Some sort of surface or near surface disturbance is necessary to start the winds circling inwards to fill the area of low pressure, but there must be no winds crossing the area, which would disturb the initial formation by disturbing the vertical air convection necessary.

The centre of the storm needs to be more than five hundred kilometres (three hundred miles) from the equator. This allows the Corriolis effect to maintain the necessary low pressure at the centre of the storm, and determines the direction of spin of the winds. South of the equator the winds spin in a clockwise manner, and north in an anticlockwise manner. Until wind speeds in the system exceed thirty-nine miles per hour the system is known as a tropical depression, at higher speeds than this the depression is classed as a tropical storm.

Answer 4

well storms begins when the clouds are full of water and how you know they are full of water is they are really dark and you will start to hear bomms and that means that there would be a storm coming?

Answer 5

Storms produce rain and snow that help feed rivers and lakes, and sustain life in most places on earth. The rain and snow also produce erosion, wearing down the land.

Finally, storms redistribute heat on earth, moving warm air towards to poles and cold air towards the equator, as well as moving warm air to the upper atmosphere. This helps the earth remain thermodynamically stable.
