Atmospheric lifting mechanisms

1
Atmospheric lifting mechanisms

• Convergent
• Convectional
• Orographic
• Frontal

2
e.g. along the ITCZ
3
Occurs over warm surfaces
4
Convectional cloud formation over Florida
5
Only occurs in hilly or mountainous regions

Adiabatic Processes

• MEANS A CHANGE IN TEMPERATURE WITHOUT THE
  ADDITION OR REMOVAL OF HEAT
• TEMPERATURE CHANGES DUE TO EXPANSION AND
  CONTRACTION OF AIR
• WHEN AIR EXPANDS IT COOLS WHEN IT IS COMPRESSED
  IT HEATS UP
• Remember the NORMAL LAPSE RATE (6.4C/1000m)
• Also have the
• Dry adiabatic lapse rate (DAR)
• 10C/1000m
• Moist adiabatic lapse rate (MAR)
• 6C/1000m
