Wind components
Posted: 09 Sep 2010 06:01 AM
The wind speed and direction can be broken into two components. These
are a south to north (v wind) and west to east (u wind) component.
[Those of you that failed geometry may wish to vote bad now]. The
featured graph presents the daily averaged u and v wind speed
component. This chart shows a clear annual cycle. Outside of the
summer months, the jet stream is often nearby and tends to help
promote dominant westerly winds. The v winds show us the dominant air
temperature advection regimes with northerly (negative v values)
during the winter time and warm southerly (positive v) in the summer
time. September is shown as a transition period with westerlies
increasing and southerlies decreasing.
