  • Tropical Equatorial Rainforest - CLIMATE
      • Little seasonal variation
      • Mean monthly temperatures barely fall below 25C and rarely rise to above 28C
      • A 'dual peak' of temperatures a little further from the equator.
      • The daily (DIURNAL) range tends to be higer than the range of monthly average temperatures.
      • Temperatures can rise above 30C in the morning or late afternoon when skies are clear after a thunderstorm.
      • If the sky is clear, night temperatures may drop rapidly, sometimes to below 20C
      • Rain falls all year round due to the Inter-Tropical Convesion Zone (a low-pressure belt) that dominates atmospheric conditions around the tropics.
      • High annual precipitation, often in excess of 2,000 mm per year.
      • There is a very short dry season a little further away from the equator, on the fringes of the tropics.
      • Low pressure conditions cause the rapid uplift of air, condensing into clouds causing heavy rain in mid-afternooon
      • Thunder and Lightening Common
      • The day starts and ends with clear skies.
      • Humidity is high throughout the year
      • The rainforest is so humid it acts as a 'natural greenhouse'.
      • It is so humid as continous evapo - transpiration from the huge amount of vegetation adds water vapour to the air.
    • WIND
      • Little breeze on the forest floor
      • Little wind around the equator as trade winds converge.
      • Around the equator, day and night are approximately the same length all year round.
      • Dawn arrives as 6am and night falls quickly at around 6pm with little twilight.
      • 12 hours of sunlight all year round allow photosnthesis to tak place all year, hence why trees are evergreen.
