MTY. 101.-General Meteorology. 3 hours. 3 credits. Prerequisite: C-21. Offered 2. A brief descriptive course presenting in an elementary manner the basic principles of modern meteorology, and designed to give the student insight into the physical pro- cesses underlying the phenomena of weather and climate. It is to satisfy the interested curiosity of the general student as well as to furnish a background useful to the prac- ticing amateur weatherman. May not be taken for credit by students majoring in meteorology. MTY. 202.-Meteorological Instruments and Observations. 2 hours, and 3 hours laboratory. 3 credits. Prerequisite: C-21. Not offered 1952-53. A course designed to indoctrinate the potential practicing meteorologist with a knowledge of the tools of his profession. Underlying principles of meteorological in- strumentation are emphasized in the discussions. Laboratory work gives practical ex- perience in both surface and upper air observations, as well as in the use of meteor- ological codes. The statement "Offered 1" means offered first semester; 2, second semester; 3, summer session.
