1 Climate  Heat balance of the Earth Heat balance of the Earth  Distribution pattern of insolation ( 日射 )Distribution pattern of insolation  Interrelationship among the globalInterrelationship among the global distribution pattern of the climatic factors  Climatic regionsClimatic regions  Impacts of climate on human beingsImpacts of climate on human beings

2 Heat balance of the Earth Balance: Incoming radiation= outgoing radiation Heat transfer: Vertical + horizontal Energy: Surplus: 0° – 38° S / N Deficit: 38° – 90° S / N

3 Distribution pattern of insolation Pattern: Uneven Affecting factors 1. Long term: Altitude, Latitude, Winds, Land & sea, Ocean currents 2. Short term: Length of daytime, Seasons 3. Local: Aspect, Cloud cover, Urbanization, Surface properties See David Waugh: An integrated Approach

4 Interrelationship among the global distribution pattern of the climatic factors Global distribution pattern of the climatic factors: 1. Temperature 2. Air pressure 3. Wind 4. Precipitation Interrelationship

5 Climatic regions Reasons for climatic variations in areas of similar latitudes Case studies: 1. Low - latitude region: Tropical humid + Tropical arid 2. Middle / High - latitude region: Temperate maritime + Temperate continental

6 Impact of climate on human beings  Population distribution  Agriculture  Daily Life - Building - Health - Recreation - BusinessRecreation - Energy consumption - TransportTransport  Meterological hazards

7 Deletetions 1. Temperature: Factors, pattern … OK 2. Air Pressure: Factors, pattern … OK 3. Wind – Planetary: Trades, Westlies,... OK Secondary: Cyclone, trough, ridge, anticyclone, monsoon 4. Condensation- fog, frost, cloud, dew 5. Precipitation: Relief, convection, … OK 6. Humidity 7. Climate of Hong Kong: Spring … Winter
