Thunderstorms most often form when a mass of warm, moist air collides with a mass of cool air, dry air, or both.

If the wind speed and direction changes with altitude (a condition called wind shear), the storms may start rotating, which gives them the potential to produce tornadoes

Thunderstorms usually occur when warm, moist air is available. Thunderstorms, especially the ones that produce tornadoes, most often occur when a cool air mass or dry air mass pushes into the warm moist one, forming a cold front or a dry line respectively.

What kind of weather will nimbostrtus clouds bring?

usually thunderstorms, maybe tornadoes (not likely).


Can there be a tornado on a hot summer day?

Yes, in fact hot, humid weather is the the most likely type of weather to produce severe thunderstorms and thus tornadoes.


Are there tornadoes in Malaysian?

Most likely yes. If an area can get thunderstorms it can get tornadoes.


Can Scattered Thunderstorms produce Tornadoes?

Yes, they can on occasions, but they will likely be of the landspout variety. Such tornadoes are typically weak.


What attracts Tornadoes?

Nothing in particular "attracts" tornadoes in a literal sense. However, they are most likely to form under a certain set of weather conditions. In most basic terms, when thunderstorms encounter wind shear, or differences in speed and direction with altitude, they can start rotating and, in turn, produce tornadoes. Thunderstorms normally develop when warm, moist air exists beneath layer of cold air. The strongest storms, those most likely to produce tornadoes, most often form along fronts, when air masses with different properties collide.


What type of front is most likely to produce thunderstorms and tornadoes?

Cold fronts are most likely to produce thunderstorms and tornadoes.


How often does bad weather lead to a tornado?

Very infrequently, though it would help to have specific definition of "bad weather". A tornado can't occur during a blizzard or a simple rain shower. Tornadoes require strong thunderstorms to form and even then the storm needs to have some sort of rotation to start the tornado. It is not uncommon to see a few tornadoes in the outer storm bands of a hurricane. In the United States it is estimated that about 1% of all thunderstorms produce tornadoes, though the frequency varies by region; thunderstorms in the Midwest are more likely to produce tornadoes than those in the Northeast.


Are tornadoes caused by human nature or both?

Tornadoes are natural events caused by the right setup of weather conditions. Human-caused climate change may affect where and when tornadoes are most likely to occur, but tornadoes remain a primarily natural phenomenon.


What are thunderstorms and where do they occur?

If the weather conditions are right, thunderstorms can happen anywhere, anytime. The weather conditions required for a thunderstorm are warm, moist air colliding with cooler air. Therefore, thunderstorms are more likely to occur in mid-latitude climates, and during the spring and summer.


What feature on a weather map is most likely to be associated with tornadoes?

Tornadoes are most likely to be associated with a cold front.


Can a tornado form in a blizzard?

Not in the blizzard itself, no. In some cases the same storm system can produce tornadoes in one area blizzard conditions in another, but these areas will remain separate from one another. For a northern hemisphere system, blizzard conditions are most likely to occur in the northwestern part of the storm while tornadoes and thunderstorms will more likely occur in the southeastern portion.


What is a Small intense weather system that produces strong winds?

A thunderstorm, most likely a severe thunderstorm.
