Atmos 5210/6210: Synoptic Meteorology II

Polar Low

Spring Semester 2018

Description

An upper-division/introductory graduate level survey of modern day synoptic meteorology and its applications, with emphasis on PV thinking, extratropical cyclones, and cool-season storms.

Learning Outcomes

At the end of this course, students should be able to:

1. Use and apply PV thinking for atmospheric analysis and forecasting.

2. Describe and analyze the life cycle of frontal cyclones, fronts, and associated precipitation systems.

3. Diagnose the dynamic, thermodynamic, and microphysical processes affecting cool-season precipitation and winter storms in a variety of synoptic, mesoscale, and orographic settings.

Format

Two classes per week (10:45-12:05 TH) in 711 WBB. Classes involve a mixture of lectures, real-time weather analysis and discussion, and active-learning activies.

Grading

Grading is based on labs (30%), a term project (40%), and a final exam (30%). Grades on assignments will be reduced 15 points (out of 100) per day past the due date. The final exam will be held in the scheduled class period on February 27.

Text

Midlatitude Synoptic Meteorology by Gary Lackmann, plus additional supplemental materials. Students should complete assigned reading before each class.

Required Computer Skills

Basic knowledge of MacOS and IDV. IDV YouTube tutorials are available here and some basic instructions are available here. Learn it and love it!

ADA Accomodations

The University of Utah seeks to provide equal access to its programs, services, and activities for people with disabilities. If you will need accommodations in the class, reasonable prior notice needs to be given to the Center for Disability services, 162 Olpin Union Building, 581-5020 (V/TDD). CDS will work with you and the instructor to make arrangement for accommodations. All written information in this course can be made available in alternative format with prior notification to the Center for Disability Services.
