This is because as Earth turns,air is pulled to the right in the northern hemisphere.In the southern hemisphere,air is pulled to the left.
Storms can get stronger and stronger as they move over warm ocean waters.The strongest,fastest winds of a hurricane are found in the eye-wall.This is the area that surrounds the center,or eye,of the storm.The eye itself is calm by comparison,with light winds and clear skies.
Winds in severe ocean storms can reach speeds of more than two hundred and fifty kilometers an hour.Up to fifty centimeters of rain can fall.Some storms have produced more than one hundred and fifty centimeters of rain.
These storms also cause high waves and ocean surges.A surge is a continuous movement of water that may reach six meters or more.The water smashes across low coastal areas.Surges are commonly responsible for about ninety percent of all deaths from ocean storms.
Weather scientists use computers to create models that show where a storm might go.Models combine information such as temperatures,wind speed,atmospheric pressure and the amount of water in the atmosphere.
Scientists collect the information with satellites,weather balloons and devices floating in the world’s oceans.They also collect information from ships and passenger flights and from planes that fly into and around storms.The crews drop instruments on parachutes to record temperature,pressure,wind speed and other conditions.
