Today's Atmospheric/Ocean Weather

Morning

Evening

ATMOSPHERE --- This morning was foggy and calm with temperatures around 70F. The fog burned off by noon, and revealed a wonderful, spectacular, just spiffy day.

Plots of today's weather data from the Field Station are shown below. Times are in GMT.

OCEAN -- In the morning the upwelling was indeed rising again, slowly. In the afternoon the surface currents were back on shore in response to the easterly wind component.

The upwelling favorable winds over the weekend have ceased by early this morning, although we may have caught a trapped shelf-wave propagating down the coast. The first two transects, N1 and N2, reveal a southward flow. The N3 line shows an intensified southward current, which appears in N1 and N2 later in the afternoon. One exciting hydrodynamic feature that we caught today was a subsurface jet at 7-10m. This ribbon of southward flowing water was located at the thermocline and tended to contain high levels of fluorescence.
