WindSat observations around a powerful early fall low pressure system…

Strong winds around a powerful low pressure system moving off the Canadian maritimes were captured yesterday by the WindSat instrument and were available via AWIPS. Around 2130 to 2145 UTC on 25th October, the WindSat instrument picked up a region of 34 to 48 kt winds on the SW flank of the low pressure system, with a few embedded wind barbs around 50 kts (Figure 1).

One of the fixed buoys in the north Atlantic recorded a pressure of 956mb several hours later around 1200 UTC 26th October, near the time of the image captured below. Note the increase in the strength of the wind field with the expansion of the area of 50 kt + wind speeds (Figure 2).
