ATM OCN (Meteorology) 100
HEAT, ENERGY AND ENERGY TRANSPORT
Lecture # 4-A Scheduled for:
17 JUN 2004 (R)
Recommended Readings from Moran (2002):
pages 73-77; 91-92.
Today's Lecture Objectives:
- To distinguish between energy and power.
- To identify the three basic mechanisms of energy transfer, describe how energy is transported by each mode and give an example of each transport mode.
- To distinguish between sensible heating and latent heating.
- To describe how temperature and heat are related through the specific heat of a substance.
- To explain the significance of wind-chill and to calculate wind-chill equivalent temperatures from values of ambient air temperature and wind speed, using the provided table.
B. ENERGY & POWER
- Types of Energy (In the Atmosphere)
C. ENERGY EXCHANGE PROCESSES
- Conservation of energy
- Energy transport requirements
- Energy exchange or transport modes
D. HEAT (or HEAT ENERGY)
- Important considerations
- Sensible heat transfer
- Measurement of heat and thermal energy
- Latent heat
E. EXAMPLE -- WIND-CHILL
- Determination of wind-chill equivalent temperature (see New Wind-chill Chart on Milwaukee-Sullivan Page)
- Cold Stress -- Human comfort and safety
