A polar cyclone is a large area of low pressure and cold air which surrounds the Earth's poles.
A polar cyclone is also known as a polar vortex or Arctic Cyclone.
A polar cyclone forms as a result of decreased sunlight and also extremely cold temperatures at the poles.
And the polar front jet stream contains the cold air within the polar vortex and the polar vortex is strongest in winter when the temperature contrast between the poles and the equators are the greatest.
When the polar vortex weakens or collapses it then allows frigid Arctic air to spill into the lower latitudes.
This can then result in severe cold snaps, weather patterns that are unpredictable or heavy snowfall.
A cyclone is a hurricane but it's called different names in different locations.
Hurricane is the name used for a tropical cyclone which forms in the North Atlantic and Northeast Pacific oceans and cyclone is the name used for the same type of storm that occurs in the South Pacific Ocean and Indian Ocean.
Both cyclones and hurricanes even typhoons are the same type of storm but the name is just different based on where the storms occur.
A cyclone and a hurricane is the same type of storm but it's just called different names depending on where the store or hurricane forms.
Cyclones which is the same as a hurricane is what forms in the South Pacific and the Indian Oceans and Hurricanes form in the Atlantic Ocean and the North Pacific Oceans.
Typhoons are also another name for hurricanes which form in the Northwest Pacific Ocean.
The names typhoons, cyclones and hurricanes are all the names of the same type of storm but the name also depends on where the storm forms.
A cold hurricane is called an extratropical cyclone which is a cyclone that gets it's energy from the temperature contrast between cold and warm air masses.
This means that the extratropical cyclone or cold hurricane has a cold core unlike a tropical hurricane that draws it's energy from the warm ocean waters.
Hurricanes do sometimes cause tornadoes, especially when the hurricane makes landfall.
A hurricane can cause tornadoes when the hurricane's rain bands create thunderstorms which also contain tornadoes.
Hurricanes can cause tornadoes when the hurricane moves from water to land and friction slows the surface winds, although the upper level winds remain strong which then creates wind shear and can cause air to spin.
The thunderstorms in a hurricane can also create strong updrafts which can also tilt the spinning air column upright and form a tornado.
Although a hurricane is mostly composed of moist and warm air, there is ice present within the hurricane's cloud structure.
Hurricanes are considered to be mixed phase clouds which means that they contain both ice crystals and liquid water droplets at different altitudes within the storm.
The higher altitudes of a hurricane cloud are cold enough to allow for the formation of ice crystals from the water vapor.
Ice is also important for hurricanes.
The presence of ice particles within hurricanes is crucial for the development and intensification of a hurricane and it contributes to the release of latent heat through the process of precipitation.
And while the eye of a hurricane is often considered calm with clear skies, the surrounding eyewall is where the most intense rain and cloud activity occurs, which includes the formation of ice crystals.
Several miles above the ground where the air is actually very cold, the hurricane clouds are made up of tiny ice particles and snowflakes.
Hurricanes are giant tropical storms which produce heavy rainfall as well as super strong winds.
Hurricanes form over warm ocean waters that are near the equator.
And the warm, moist air above the ocean surface rises and causes air from surrounding areas to get sucked in.
A hurricane and tornado are different types of storms and form in different conditions although they can seem similar to some people.
