Why? GEOG 1F91 Principles of Physical Geography Air Temperature and Cycles npilger@brocku.ca Air Temperature Air temperature is influenced by seven key factors 1. Insolation: GEOG 1F91 Principles of Physical Geography Air Temperature and Cycles npilger@brocku.ca Air Temperature Air temperature is influenced by seven key factors 2. Latitude: Less insolation = less energy to heat the air GEOG 1F91 Principles of Physical Geography Air Temperature and Cycles npilger@brocku.ca Air Temperature Air temperature is influenced by seven key factors 3. Cloud Cover: influences energy transfer influences energy transfer: from space to surface to space GEOG 1F91 Principles of Physical Geography Air Temperature and Cycles npilger@brocku.ca Air Temperature Air temperature is influenced by seven key factors 4. Surface Type: moisture content (latent heat from evaporation) and albedo GEOG 1F91 Principles of Physical Geography Air Temperature and Cycles npilger@brocku.ca Air Temperature Air temperature is influenced by seven key factors 5. Proximity to (large) water bodies: GEOG 1F91 Principles of Physical Geography Air Temperature and Cycles npilger@brocku.ca Air Temperature Air temperature is influenced by seven key factors 6. Elevation: Atmosphere is Less dense at higher elevations = more LW EMR out, but also more SW EMR in & range in temp is quite pronounced GEOG 1F91 Principles of Physical Geography Air Temperature and Cycles npilger@brocku.ca Air Temperature Air temperature is influenced by seven key factors 7. Slope and aspect: Radiation intensity and warming increase to point where slope is perpendicular to solar rays. Aspect & north or south facing GEOG 1F91 Principles of Physical Geography Air Temperature and Cycles...
