A hurricane is basically a massive heat engine that transfers the high oceanic heat content into the atmosphere by releasing that built up heat via condensation. Once a hurricane moves onshore, it loses that energy source and weakens.
Hurricanes only form over really warm ocean water have to be over 80F or even warmer. the wind has to blow in the same direction. it has to have the same spped to force air upward from the ocean surface.
To undergo tropical cyclogenesis, there are several favorable pre cursor environmental conditions that must be in place (Gray 1968,1979) :
# Warm ocean waters (of at least 26.5°C [80°F]) throughout a sufficient depth (unknown how deep, but at least on the order of 50 m [150 ft]). Warm waters are necessary to fuel the heat engine of the tropical cyclone.
# An atmosphere which cools fast enough with height such that it is potentially unstable to moist convection. It is the thunderstorm activity which allows the heat stored in the ocean waters to be liberated for the tropical cyclone development.
# Relatively moist layers near the mid-troposphere (5 km [3 mi]). Dry mid levels are not conducive for allowing the continuing development of widespread thunderstorm activity.
# A minimum distance of at least 500 km [300 mi] from the equator. For tropical cyclogenesis to occur, there is a requirement for non-negligible amounts of the Coriolis force to provide for near gradient wind balance to occur. Without the Coriolis force, the low pressure of the disturbance cannot be maintained.
# A pre-existing near-surface disturbance with sufficient vorticity and convergence. Tropical cyclones cannot be generated spontaneously. To develop, they require a weakly organized system with sizable spin and low level inflow.
# Low values (less than about 10 m/s [20 kts 23 mph]) of vertical wind shear between the surface and the upper troposphere. Vertical wind shear is the magnitude of wind change with height. Large values of vertical wind shear disrupt the incipient tropical cyclone and can prevent genesis, or, if a tropical cyclone has already formed, large vertical shear can weaken or destroy the tropical cyclone by interfering with the organization of deep convection around the cyclone center.
Tropical Storms start within 8º and 15º north and south of the equator where surface sea temperatures reach 27ºC. The air above the warm sea is heated and rises. This causes low pressure.
As the air rises it cools then condenses, forming clouds. Air around the weather system rushes in to fill the gap caused by the rising air. The air begins to spiral. This is caused by the spinning movement of the earth.
When warm, moist tropical air combines with cold air at a low-pressured
zone usually near the equator and the gulf steam. The combined air turns
into something called a tropical storm. The tropical storm gets bigger and
bigger until it is a all out hurricane.
essential ingrediants= warm water, &moist warm air. take shape on west coast of Africa, from thunderstorms. warm air rises, meets cold air, evaporates warm water vapor, forms storm clouds, &drops of rain, condensation releases latent heat, warms the cool air, makes it rise, creates wind a heat pattern. hello hurricane
mother nather
Yes. Hurricanes usually occur in the summer and early fall. the Atlantic hurricanes season tends to peak in August.
yes, they do
every day
Hurricanes, tornadoes, and virtually all other forms of weather occur in the lowest layer of the atmosphere, the troposphere.
Sometimes a hurricane can produce tornadoes, but most tornadoes are not produced by hurricanes.
Hurricanes occur over warm ocean water in or near the tropics.
Hurricanes most often occur in August.
they usually occur in summer
Hurricanes do not occur on land. They are only water storms and blow into land.
A range of 1-2 hurricanes typically occur in June.
i think in the late months are when hurricanes occur most if the time because right now there are hurricanes and it is august and ur a noob
Hurricanes occur because of the wind current and speed of the wind, the hotter the area is the worse the hurricane becomes. So no hurricanes don't occur because of environmental pollution.
Hurricanes occur in tropical climates.
Yes. Hurricanes usually occur in the summer and early fall. the Atlantic hurricanes season tends to peak in August.
Hurricanes mostly occur in places that are close to the ocean and excel in hot weather places such south americas coastline and china are prone to hurricanes or typhoons
Yes. Hurricanes occur every year.
Yes, in fact, hurricanes cannot occur without it.
