ATMOSPHERIC ENERGETICS:

HEAT, ENERGY & ENERGY TRANSPORT

Fall 1997

Lecture #6 Scheduled for:

15 SEP 1997 (M)

Recommended Readings from Moran and Morgan (1997):

pages 73-78; 33-64; 91-93.

NOTE: This lecture continues as Atmospheric Energetics: Radiation

Objectives:

• To distinguish and contrast the concepts of heat and temperature.
• To identify the three basic mechanisms of energy transfer, describe how energy is transported by each mode and give an example of each.
• To demonstrate how temperature and heat are related through the specific heat of a substance.
• To distinguish between sensible heating and latent heating.

Outline:

A. ENERGY & POWER

• Importance
• Types of Energy (In the Atmosphere)
• Units
  • Energy units
  • Power units

B. ENERGY EXCHANGE PROCESSES

• Conservation of energy
• Energy exchange or transport modes
  • Conduction
  • Convection
  • Radiation

C. HEAT (or HEAT ENERGY)

• Definition
• Important considerations
• Sensible heat transfer
  • Measurement of heat and thermal energy
• Latent heat

Continues in next lecture as Atmospheric Energetics: Radiation
