A Hurricane is a cyclonic circulation or midlatitude cyclone. It is a large air mass in the northern hemisphere that rotates counterclockwise around a low pressure system.

Hurricanes are caused by 1) high water temps (80F at 1st 200 ft), 2) high warm air temperatures, humidity (unstable enough to sustain convection) 3) upper level winds are weak & blowing in direction that the sorm is moving and 4) the Coriolis effect contributes to the spinning.

NOTE: 80degree F temp is key, sea-surfae temperature rises with air at 80deg F or more, aire water vapor then increases expontentially, when 80 deg F temp is exceeded, laten heat lifted from ocean grows large & creates a hurricane.

Development of Hurricane:

1st - Tropical Disturbance Forms - (clusters of small thunderstorms with weak surface winds) - a low pressure zone pulls these clusters together

2nd- Tropical Depression Forms - (winds must be sustained at 23 mph) surface winds strengthen around and into center of storm

3rd - Tropical Storm Forms - the Coriolis effect spins counterclockwise in the northern hemisphere, ware air continues to rise, then cools & water vapor condenses releasing latent heat, the latent heat warms the surrounding air of the tropical depression causing stronger updrafts which increase the rate of upward flow of warm moist air and winds are now sustained at 39mph or up to 73mph. The wind speed determines whether or not there is a Tropical Storm or a Hurricane.

4th - HURRICANE - caused by all of the above - and if the winds increase to be over 74mph there is a hurricane

In the Northern Hemisphere these storms are referred to a Hurricanes

Cyclones and Typhoons are other forms of hurricanes - just named differently because of the areas in which they form.

Cyclones - form in the Indian ocean

Typhoon - form in the W. Pacific Ocean

How do northern hemisphere hurricane winds spin?

Hurricanes in the northern hemisphere spin counterclockwise.


When does hurricane season starts?

Hurricane season officially starts on June 1st for the northern hemisphere, and November 1st for the southern hemisphere. Hurricane season lasts for 6 months, ending on November 30th for the northern hemisphere, and June 30th for the southern hemisphere.


What month do hurricanes frequently occur in the northern hemisphere?

when is the month for hurricane to occur in the northern hemisphere?


Is there different rotation between a hurricane and a cyclone?

No. A hurricane is a kind of cyclone. All cyclones rotate counterclockwise in the northern hemisphere and clockwise in the southern. The term hurricane applies to a tropical cyclone in the northern hemisphere.


What direction does a hurricane spin in the northern hemisphere?

Low pressure systems such as hurricanes spin counterclockwise in the northern hemisphere.


What is a coriolis in a hurricane?

This is the effect of the spinning earth on the axis. It cause Tropical storms to rotate anti clockwise in the northern hemisphere and clockwise in the southern hemisphere. It also causes the track of the Hurricane to bend to the right in the northern hemisphere and left in the southern hemisphere.


Where can you find a picture of a hurricane spinning in the northern hemisphere?

Click on the link to see the photo. Also, if you search "hurricane in the northern hemisphere" on google images without the quotes, you will find pictures.


Does the direction of the hurricane depend on the hemisphere where the hurricane occurs?

Yes. Hurricanes (generically called tropical cyclones) rotate counterclockwise in the northern hemisphere and clockwise in the southern hemisphere.


Which direction do the winds around a hurricane travel?

Since a hurricane is, by definition, a tropical cyclone in the northern hemisphere, winds in a hurricane rotate counterclockwise. Equivalent storms in the southern hemisphere have clockwise winds.


Which way do the winds turn during a Hurricane?

Clockwise in the southern hemisphere and Anti- clockwise in the northern hemisphere


Can a hurricane spin in a different direction?

If it is in the northern hemisphere it will spin counterclockwise. If it is in the southern hemisphere it will spin clockwise.


Is the direction of a hurricane always counterclockwise or clockwise?

Tropical cyclones (the generic term for hurricanes and similar storms) rotate counterclockwise when they occur in the northern hemisphere and clockwise when they occur in the southern hemisphere. Since the term hurricane applies to a tropical cyclone in the northern hemisphere, a hurricane will always rotate counter clockwise. However, aside from the direction of rotation there is no real difference between northern and southern hemisphere tropical cyclones.


Hurricane rotate clockwise or anti clockwise?

In the northern hemisphere they rotate counterclockwise. In the Southern hemisphere they rotate clockwise.


How do northern and southern hemisphere differ for hurricance?

There is no such thing as a hurricane! What is your problem people. GET REAL!! Like sereiously, who would want to know "how the northern and southern hemisphere differ for hurricane"? Well the answer is that hurricanes are not real, they are a mith.


What is a hurricane that rotates clockwise?

It is a hurricane that forms under the equater. In the northern hemisphere hurricanes turn counter-clockwise. They are called Typhoons in the southern hemisphere and recently a Hurricane was seen to cross the equator which is very worrying for our future climate.


What direction does a hurricane spin in the southern hemisphere?

Hurricanes spin clockwise in the Southern hemisphere. Hurricanes in the Northern hemisphere spin counterclockwise. Hurricanes in the Southern hemisphere are called cyclones.


Do hurricane's rotate in a counter-clockwise direction?

Hurricanes are in a class of storm called tropical cyclones. Such storms rotate counterclockwise in the northern hemisphere and clockwise in the southern. In a strict sense, the term hurricane is only applied to tropical cyclones in parts of the northern hemisphere, so they do rotate counterclockwise.


Which way do the winds turn in a hurricane?

Since the term hurricane refers to a tropical cyclone in the northern hemisphere, the winds turn counterclockwise.


If a cyclone or hurricane begins in the southern hemisphere and moves to the northern hemisphere does the Coriolis Effect cause the cyclone to switch the direction that it is spinning?

No.


Does a hurricane rotate in a counter clockwise direction?

Hurricanes in the northern hemisphere rotate counterclockwise. Their counterparts in the southern hemisphere rotate clockwise.


Is it true or false that hurricanes rotate in a counter-clockwise directions?

It is true that in the Northern Hemisphere, a hurricane rotates counterclockwise (anticlockwise in British English).In the Southern Hemisphere, the hurricane rotates clockwise.


In what direction does a hurricane rotate?

Counterclockwise in the northern hemisphere and clockwise inthe southern hemisphere, though they are more often called cyclones in the latter.


Does a hurricane spin clockwise?

Only in the southern hemisphere, but they aren't called hurricanes there. They are only called hurricanes in the northern hemisphere where they spin counterclockwise.


When is a hurricane called a typhoon?

When it is in the Pacific Ocean in the northern hemisphere and is west of the International Date Line.


Winds circulate around a tropical storm or hurricane in which direction in the Northern Hemisphere?
