weather that exist in the world today

Most tornadoes form from thunderstorms.

You need warm, moist air from the Gulf of Mexico and cool, dry air from Canada in order for a tornado to form and happen.

When these two air masses meet (the warm and cool air) they create instability in the atmosphere.

Hurricanes are the most awesome, violent storms on Earth.

The form near the equator over warm ocean waters.

Actually, the term hurricane is used only for the large storms that form over the Atlantic Ocean or eastern Pacific Ocean.

The generic, scientific term for these storms, wherever they occur, is tropical cyclone.

The oceans are the chief source of rain, but lakes and rivers also contribute to it.

The Sun's heat evaporates the water.

It remains in the atmosphere as an invisible vapor until it condenses, first into clouds and then into raindrops.

Condensation happens when the air is cooled.

Snow is formed when temperatures are low and there is moisture - in the form of tiny ice crystals - in the atmosphere.

When these tiny ice crystals collide they stick together in clouds to become snowflakes.

If enough ice crystals stick together, they'll become heavy enough to fall to the ground.

As the earth is affected by an unequally of heat energy from the sun, the state of the air differentiate between different regions.

Warm air expands and rises up while cold air condenses and sinks, hence resulting the flow of air and forms wind.

Its produced by a cumulonimbus cloud, usually producing gusty winds, heavy rain and sometimes hail.

The basic ingredients used to make a thunderstorm are moisture, unstable air and lift.

You need moisture to form clouds and rain.

You need unstable air that is relatively warm and can rise rapidly.

When warm air rises, it expands and cools.

Cool air can't hold as much water vapor as warm air, so some of the vapor condenses onto tiny pieces of dust that are floating in the air and forms a tiny droplet around each dust particle.

When billions of these droplets come together they become a visible cloud.

Sunny skies many times are observed when a high pressure area is dominating the weather pattern.

High pressure signifies a region of sinking air which tends to dry out the atmosphere resulting in less moisture to form clouds.

Deserts are locations with sunny or mostly sunny skies due to high pressure systems influencing the weather pattern much of the year.

Little pellets of frozen rain that fall in showers from cumulonimbus clouds.

They may look just like snowballs, but the can do a lot of damage.

A thick cloud of tiny water droplets suspended in the atmosphere at or near the earth's surface that obscures or restricts visibility (to a greater extent than mist; strictly, reducing visibility to below 1 km).

So basically, a cloud on the ground.

Your walking on a cloud whenever theirs fog around.
