Chapter 3 Notes-Temperature - Surface temperature is measured 1.5 meters above the ground (usually on a grass surface) in the shade to avoid solar heating of the thermometer. Avg. global temp=15 C. - Over short periods of time and regions, imbalances in surface energy budget can result in temperature increasing or decreasing when energy is either stored or removed from the system. - Temperature changes are driven by the difference in incoming solar radiation gains versus outgoing terrestrial energy losses. - The surface exchanges energy with the air by conduction, convection, turbulent mixing of the winds, and radiative and latent heat fluxes. - Diurnal Temperature Cycle- the repeating pattern of daily temperatures. - Diurnal Temperature Range- the differences between the minimum and maximum temperatures on any given day. - Daily Mean Temperature- averaging the maximum and minimum temperature for a 24 hour period. - Similar temperature cycles also occur on monthly, annual, and interannual time scales. - 5 major factors cause energy imbalances for annual temperature cycle: Latitude, Surface Type, Elevation and Aspect, Relation to large bodies of water, and cloud cover. o Latitude- angle of inclination affects incoming solar energy and causes the seasonal cycle in temperature. The amount of energy at the top of the atmosphere is
