The length of the arrows indicates speed. Show how wind speed and direction change with altitude. The faint image of Bonnie in this microwave image can be seen in the The blue area is 3 to 6 ° C (5 to 10° F) cooler than the surrounding The image shows a cold water wake left by When hurricanes travel, they suck heat from the ocean surface, leaving a The ocean south of Hawai'iĪlways warm enough for hurricane formation. Hurricanes only form when the ocean surface temperature is at least 27° C (80° F),Īlthough they may later move over cooler water. It and the warmer the water, the greater the heat transfer through evaporation Warm water to provide energy, a favorable atmospheric profile, and an initialĭisturbance that starts a positive feedback loop to strengthen the storm.Įvaporation from the ocean surface transfers the necessary heat into the storm Hurricanes have demanding requirements for formation and growth, including The Hawaiian Islands, and some of the effects experienced during a hurricane. In this section we look at some of the physical conditions requiredįor hurricane formation and movement, how those requirements tend to protect On the open ocean, and dump over a half meter (20 inches) of rain when it hits land. Generate 130 kph (80 mph) winds over a swath 160 kilometers (100 miles) wide, kick up 15 meter (50 foot) waves Large hurricane can roil over a million cubic kilometers of atmosphere per second, Many of the thunderstorm and flooding eventsĭuring the warm season in Hawai'i are caused by the passage of theseĪny weather phenomenon that earns its own name must be fearsome indeed. Winds may not be severe as hurricanes, but they can dump hugeĪmounts of rainfall when they pass over land. Than their more famous relative, tropical storms and tropical depressions can stillĬause significant damage. Tropical storms, and few of these grow into hurricanes. In Hawaiian waters during the hurricane season, only a few tropical depressions strengthen to become Describe the global distribution of hurricanes.Which part of the hurricane has the highest wind speeds?.Why to the clouds swirl in opposite directions at the surface.How is eye pressure related to hurricane strength?.Why do hurricanes seldom affect Hawai'i?.What are the requirements for hurricane formation and growth?.Distinguish between tropical cyclones, depressions, storms, and hurricanes.
