1. ClimateA. Climate if affected by:
a. Latitudeb. Circulation of atmosphere and ocean current
B. Components:a. Temperatureb. Moisture (Precipitation)c. Light
C. Microclimate:a. The climate of ‘small’ areab. Location vs. site:
- Location: geographic, climatic area- Site: microclimate within a location
D. Ecology:a. Study of life forms in relation to environmentb. Climate influences distribution of horticultural
crops and industry
2. Climatic Regions
A. Tropical Regions
B. Subtropical Regions
C. Dry Climate
D. Mediterranean
E. Temperate Zone
F. Mountain (Tundra)
Climatic Zones of the World
A.Tropical and Subtropical Climate
a. Hot and wet all year round
b. Low light under tree canopy
B. Dry Climatea. Arid regions
b. Semi-arid regions
Semi-Arid Climate - Low annual precipitation - Sonoran Desert of the Southwest
C. Mediterranean ClimateA. Climate: Mild winters
Dry hot summers
B. Regions: Italy, Southern France, Spain
Coastal California
D. Temperate Zone Climate - Deciduous trees and shrubs
- Distinctive four seasons
E. Mountain Climate (Tundra)
- Very cold year round
