Extreme Weather & Rain
- When rain comes over Britain, it usually comes the Asian area.
- Down south it usually much wetter but also
warmer, where as in the norther area, it is a lot
colder and usually more rainfall happens a year.
- Extreme weather is a rare phenomenon that often
causes extreme disruption to transport and the general
usual system.
- Hurricanes
- Hurricanes are extremely powerful
long lasting super storms which can
destroy countries and put them in
massive debt.
- They are formed over sea, when the
building air pressure starts to circulate and
the water vapour helps it to maintain power.
As it travels over land it loses power and
disperses.
- They form
around the USA
area where the
pressure is high
and the seas
are varying in
temperature.
- Responses
- Particular areas are evacuated
- Precautions took at home,
eg boarding up windows,
keeping doors shut etc.
- Certain companies set up to depart as
soon as the storm ends, to try and
restore order and also to give out food
and regain electricity power.
- Effects
- Disrupts whole countries, causes deaths and destroys electricity
- Costs affected places a lot of money to restore.
- Rain is caused by the evaporation of
water, it then rises and begins to cool.
Once it has cooled, it condeses to form
clouds. This whole process is called
presipitation.
- Types of rain
- Relief
- Mountains, the clouds go up the mountain and
condense, when they come back down, it begins to
rain.
- Convection
- Sea and land, the
water evaporates and
creates rain.
- Frontal
- Warm air meets the cold air,
this goes into the process of
precipitation.
