MTEOR 454: Dynamic Meteorology

500 mb waves and Rossby wave theory

Abstract

According to Rossby wave theory, smaller wave numbers are associated with increased wave speed and decreased amplitude. Analysis of the 500 millibar heights and flow in the Northern and Southern Hemispheres and the zonally averaged wind by latitude over the course of the time period from late August through early November 2008 will test this theory. Most of the results do not correlate well. It is believed that errors in the methodology and analysis give the impression that Rossby wave theory has failed, when in reality, it may be more difficult to verify than what is done in this study.

ENGL 314: Technical Communication (Writing)

A beginners guide to understanding and interpreting Doppler weather radar

The above was written before I took any official radar meteorology course. Therefore, expect it to contain errors, some of which are subtle (inaccurate definitions or synonyms) while some may be more glaring. I no longer possess the original file used to make this, so I cannot change it now. However, it should still be very useful to beginners.
