What are the geographical processes that cause storms
The winds spin counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. The physical processes that power a hurricane. Hurricanes/tropical cyclones cause torrential rain. As a tropical storm approaches land, it also pushes a wall of water called a storm surge onto the shore.Flooding results, which can go inland for several miles.urricanes/tropical cyclones cause torrential rain.

Storms are classified by their wind speed. Once the speed reaches 63 km/h (39 mph), the weather condition is called a tropical storm and is given a name. This process begins the warning system. If the wind speed reaches 119 km/h (74 mph), the storm is reclassified as a hurricane.urricanes/tropical cyclones cause torrential rain.

Thunderstorms require 3 main ingredients; a source of moist air, an unstable atmosphere and a trigger mechanism. Moist air is important because when it condenses to form cloud, heat energy is released making the rising air more heavier in some cases and faster moving.ll storms begin with Lightning and/or thunder. Lightning is the discharge produced when voltage differences between ground and atmospheric electrical charge are large enough to overcome the insulating effect of the air. Strokes can occur within the cloud, between clouds, or between clouds and the ground. And trigger mechanisms are important as they serve as a focus for storm development. Often cold fronts trigger a typical severe stroms and areas of low air pressure, hills and mountains can also increase the development, with fast movements of wind.ll storms begin with Lightning and/or thunder. Lightning is the discharge produced when voltage differences between ground and atmospheric electrical charge are large enough to overcome the insulating effect of the air. Strokes can occur within the cloud, between clouds, or between clouds and the ground. There are several stages in the formation of a tropical storm. These storms occur over water in areas where the sea surface temperature is at least 27 degrees. Essentially, this means that they form between the Tropic of Cancer and the Tropic of Capricorn (hence the name 'tropical' storm).They rarely occur within 5 degrees either side of the equator because the Coriolis force is too weak here. Tropical cyclones use warm, moist air as fuel.e have already seen that the effects of earthquakes and volcanoes can be classified into primary and secondary effects. The same is true of the effects of tropical storms. Primary effects are those that result directly from the event itself. Secondary effects are those that result from the primary effects. The video clip below explains this process in images. When the winds in the rotating storm reach 39 mph, the storm is called a tropical storm. When the wind speeds reach 74 mph, the storm is officially a tropical cyclone, or hurricane.e have already seen that the effects of earthquakes and volcanoes can be classified into primary and secondary effects. The same is true of the effects of tropical storms. Primary effects are those that result directly from the event itself. Secondary effects are those that result from the primary effects. In the South Pacific and the Indian Ocean, these storms are called tropical cyclones. Typhoon is the name given to this phenomenon in the North Pacific. Hurricane Rita at its peak in the Gulf of Mexico in September 2005.urricanes/tropical cyclones cause torrential rain. As a tropical storm approaches land, it also pushes a wall of water called a storm surge onto the shore. Flooding results, which can go inland for several miles. If the atmosphere is very unstable with light winds and little shear, storms develop a pulse-like character, rising strongly upwards then collapsing over the period of half to one hour. Severe thunderstorms in these conditions may produce large hail and strong bursts of wind but rarely produce widespread damage.ll storms begin with Lightning and/or thunder. Lightning is the discharge produced when voltage differences between ground and atmospheric electrical charge are large enough to overcome the insulating effect of the air. Strokes can occur within the cloud, between clouds, or between clouds and the ground. 1 Storm surges that are caused by a tropical or extratropical cyclone are included in this category of floods. 2  Coastal floods are caused by severe sea storms, or at the hands of another hazard such as a tsunami or a hurricane.3  Storm surges, as mentioned before, are also included in coastal floods.
