TROPICAL STORMS

Once a tropical storm system has developed over the ocean, high altitude jet-stream winds, hit it sideways and start it spinning, whilst the rotation of the earth (Coriolis Effect), starts it moving from east to west. When it hits land, it brings three major threats: Very high winds (160-180 km/hour) – loose structures destroyed, trees uprooted, roof tiles blown away etc. Very heavy rainfall (up to 100cms) – inland flooding and mudslides; Storm surge waves of sea water (up to 4m. high) breaking along the shore – building destruction, flooding and saltwater inundation.

Structure of a tropical storm Strong overhead sun (summer months) heats 50m of the sea to 27C Shade the sea in blue, draw red arrows for warm air currents and blue arrows for cold air currents in blue
