GGR112H5 Lecture Notes - Lecture 9: Canadian Pacific Air Lines, Northern Hemisphere, Cyclogenesis
Document Summary
Weather short term day to day conditions of the. Climate long term average (e. g. , 30 years) atmospheric atmosphere conditions. Meteorology scientific study of the atmosphere. Air mass a similar body of air with respect to temperature, moisture and stability, and it distinctly reflects the characteristics of its source region. Weather conditions reflect the dynamics within and between air masses. Air mass types classified based on moisture, and temperature or latitude. Moisture : m maritimes (wet, c continental (dry) Temperature/latitude : a arctic, p polar, t tropical, e equatorial, aa antarctic. Example: an air mass coming over a polar ocean (north. Pacific) would be called mp maritime polar. Air mass moisture contents: ca 0. 1-0. 3 g/kg, cp 1. 4 g/kg, mp 4. 4 g/kh, mt 10-17 g/kg, ct 10 g/kg, continental polar (cp) The air masses from cp form only in the northern hemisphere and are most developed in winter and cold weather conditions.
