GEOG 111 1st Edition Lecture 27 Outline of Last Lecture I. Snowa. Significanceb. Formation c. Atmospheric patternsOutline of Current Lecture I. Wave cyclonesa. Where do they occurCurrent LectureI. Wave cyclonesa. Where do they occur?i. Along a front where there is a temperature gradientii. Fronts encourage the lifting of air clouds and precipitation iii. Middle troposphere around cold front is much colder1. The ELR tends to be steeper2. Unstable conditions, stronger lifting thicker clouds and heavier precipitationiv. Beneath the jet stream (aloft) and downstream of a trough1. Rising air equates with area of upper level divergencea. Occurs just downstream from trough2. Air is slowing down, creating upper level convergence, sinking air motions causing high pressure at surfacea. Occurs upstream from troughv. Know this diagram well for test 3These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a
