Howling East Wind

Posted: 11 Apr 2019 05:32 AM

With the extremely powerful storm system just off to our west, winds on Wednesday were howling out of the east rushing toward the low pressure system. A way to summarize the wind direction and speeds on Wednesday is through a wind rose chart. A wind rose is a histogram plotted on a polar plot. The length of the bars represent a frequency for a given speed and direction combination. The wind speeds are partitioned to break down the frequency by speed for a given direction. The plot nicely shows the dominate easterlies yesterday with hardly any winds reported less than 10 MPH.
