looking for upwelling patterns in AVHRR SST datasets

I'm looking for a little help on analyzing a 5 month time-series of AVHRR
satellite sea surface data in hopes of learning a little about upwelling
patterns along the coast of the Mid-Atlantic Bight. Ocean water upwelling
occurs periodically near the coast of continents when the winds are
favorable and cause water from near the coast to pile up offshore. When
this occurs, cold, nutrient rich water is upwelled from the depths to
replace the warm water that was advected offshore.

So the primary signal I'm looking for is colder than average temperatures
along the coast in the summer time. Here's an

I've spent a little time looking over the NCL climatology
am a little overwhelmed by them all. I think I need to compare daily
monthly climatologies to daily composites an look for low temperature
anomalies, but I'd like to get a computer to do it for me. The dataset
consists of individual satellite passes (we get anywhere from 4 - 8 per

Any suggestions on where to begin?

Thanks in advance for any advice.
