The infrared data also resolved brown, elongated features in the whitened area called "brown barges" as distinct features and revealed them to be regions clearer of clouds and probably characterized by downwelling, dry air.

In the California Current system, strong El Nino years in the positive ENSO phase have been linked to increased downwelling, warmer SSTs, and a deepening of the thermocline observed off Southern California (Sette and Isaacs, 1960; McGowan, 1985; Caldeira et al.
In addition to wind mixing, surface and bottom currents, upwelling and downwelling are also present here and modify the vertical distribution of chemical substances (Kowalewski & Ostrowski 2005).
These convoluted flows cause local upwelling in some locations and downwelling --where floating particles tend to collect - in others.

Larval distributions probably resulted from a combination of patterns of spawning and vertical distribution, combined with wind-driven onshore advection and downwelling on the seaward side of the outer reefs.
Experiments in 1995 and 1996 show that such sequences of upwellings can often take place, because up-and downwelling usually mirror each other at the opposite coasts.
