tropical storms Flashcards
what are tropical storms
he storms called hurricanes cyclones and typhoons in different parts of the world
where to post tropical storms occur
5-15 degrees north and south of the equator
what conditions are needed for tropical storms
-highest ocean temps (above 27 c)
-the spinning effect of the earths rotation is very high
-intense heat and humidity make air unstable, causing it to rise rapidly
how does global atmospheric circulation of unstable air affect tropical storms
-unstable rising air in equatorial regions encourages air to rise and condense and form storm clouds
how does global atmospheric circulation of wind affect tropical storms
-winds blow from high pressure belts to low
-these trade winds are responsible for the east west star paths
what is the centre of an eye in a. tropical storm
-a column of rapidly sinking cool air where conditions are relatively calm and there are no clouds
what is the eye wall of a tropical storm
the outer edge of the eye with the most severe conditions with very strong winds and torrential rainfall
what swirls around beyond the eye wall
-cumulonimbus clouds that bring additional bands of rain
how does climate change affect tropical storms
warmer, moist rising air provides extra energy for tropical storm formation
how does development in technology help monitor tropical storms
-satellite tracking and radar provide data for computer programs to analyse and predict the track of the storm and its impacts
what are the two levels of warning for tropical storms
hurricane watch- advice issued over a wide area
hurricane warning- advice targeted on a specific area and expecting immediate action
how can buildings be protected from tropical storms
-strom drains
-sea walls
-reinforced walls, roofs and window shutters
how can buildings be protected from cyclones
-shutters over windows
-strong concrete build
- built on raised ground
-built on stilts incase of flood
how is planning issued for tropical storms
- educating people of the dangers
-reinforcing buildings
