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

∙ 11y agoIt is a consequence of the Coriolis effect, a consequence of the earth's spin. In large scale weather patterns such as hurricanes, air is deflected relative to the direction it is pulled by a pressure gradient where it would otherwise simply move towards low pressure (such as in a hurricane) and away from high pressure.
Air in the northern hemisphere is deflected to the right while air in the Southern Hemisphere is deflected to the left. This is a consequence of the fact that, when viewed from over the north pole, earth appears to rotate counterclockwise, while it appears to rotate clockwise if view from over the south pole.

What month do hurricanes frequently occur in the northern hemisphere?
when is the month for hurricane to occur in the northern 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.
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.
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.
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?
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.

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

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.
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.
Is it true or false hurricanes rotate in a counter clockwise direction?
It is true that in the northern hemisphere, a hurricane rotates counterclockwise (anticlockwise in British English).In the Southern Hemisphere, the hurricane rotates clockwise.
What does a hurricane rotate in?
Counterclockwise in the northern hemisphere and clockwise inthe Southern Hemisphere, though they are more often called cyclones in the latter.
How can you tell what hemisphere a hurricane is in?
By looking at a satellite image. If the cloud bands spiral inwards and counterclockwise it is in the northern hemisphere. If they spiral inwards and clockwise it is in the southern hemisphere.
