Satellite data showed that California coastal winds weakened during the Pacific Blob enough to prevent cold upwelling water from breaking through the unusually warm surface water.
Notes on verification
Confirmed by original National Geographic article and independently corroborated by NASA Earthdata and NASA Earth Observatory sources, which describe the same mechanism of weakened coastal winds suppressing upwelling during the Blob event.
