Hurricane extended

• Moisture laten dit from the ita to supply or replace the sic Sot is lost to the hope sphett

  The is bescessory he the fametion of thick and extensive cloud cove Bhuigh Condensation
• Wind pattern hear the ocean's surface

  1. Must spiral inwards

  2. Rotation of the earth causes winds to rotate anticlockwise in a spiral and upward motion in the centre of the hurricane
• Weather association hurricane
• Before the hurricane


  1. Feathery circus cloud at great height

  2. Air is calm

  3. Humidity is high, so the air is hot and sticky
• During the hurricane


  1. Occasions gusts of wind and showers of rain

  2. Wind speed is very strong

  3. Rainfall is very heavy

  4. Can cause serious flooding and damage to infrastructure

  5. When the eye of the hurricane passes, there will be a short period of calm

  6. After the eye of the hurricane pass the wind starts over again and heavy rain continues
• After the hurricane


  1. Wind gradually weakens

  2. Steady rain continues to fall for several days
• Cold front


  • When air remains relatively stagnant over an area for some time, it takes on the temperature and moisture characteristics of the area
  • Air which remains stagnant over the sea or ocean in the tropics will become warm and moist
  • A body of air which has similar temperature and moisture characteristics throughout is known as an air mass
  • As air masses move, they encounter other air masses with different characteristics
  • The boundary between two air masses is known as a front
  • Warm fronts occur when a warm air mass moves into a region of colder air
  • Cold fronts occur when a cold air mass moves into a region of warm air
• Cold front affects the Caribbean region

  1. Cold air from North America (Northers) moves into the Caribbean

  2. There is a well-defined boundary where this cold, dry air meets the warm, moist air of the Caribbean

  3. The cold air is denser and heavier and so it pushes its way beneath the warm air

  4. The warm air, which is lighter and less dense than the cold air, is forced to rise

  5. The rising of air will result in cooling

  6. Cooling will result in condensation and then condensation will result in cloud formation (cumulonimbus clouds)

  7. Eventually rain will fall (heavy rain and thunderstorms)
• As the cold front passes

  • The temperature may drop by several degrees (sometimes 50C)
  • The wind speed increases
  • There is heavy rainfall along the line of the front and either side of it
  • There is an increase in the amount of cloud with the development of particularly cumulonimbus clouds
• Cold Fronts affect the countries in the Northern Caribbean e.g. Jamaica, Bahamas Cuba and Haiti
