Weather and climate effects on agricultural production. Relation of water balance and other climate factors to growth and yield of crops, introduction to crop-weather modelling, climae hazards and their control, weather apsects of pest and disease management.

Solar and terrestrial radiation; pressure systems and winds; atmospheric stability and vertical motions; air masses and fronts; clouds and precipitation; selected topics in applied meteorology including air pollution. The laboratory emphasizes the analysis and use of atmospheric data for solving environmental problems.

Natural and intentionally-modified microclimates near the earth's surface; energy budgets; transport of mass and heat. Familiarization with some instruments for microclimatic measurements.

Atmospheric thermodynamics, radiative transfer in the atmosphere, atmospheric gases and climatic change. It is recommended that students take 64-305 before this course, in addition to the prerequisite. (Offered in odd-numbered years.)

Equations of atmospheric motion, vorticity, mechanisms of pressure change, numerical weather prediction, weather map analysis and forecasting. (Offered in even-numbered years.)
