Sea Surface Temperature Analog
The image below shows the sea surface height anamoly. The higher the anomaly, reds and whites, the higher the sea surface temperature. Lower heights are purples and blues.

These images are from OSTM/Jason-2 Satellite which uses radar altimetry to measure sea level height. The colors follow the standard spectrum. Whites and red represent high sea level height anomalies. Purples and blues represent low sea level height anomalies.
Roughly speaking, warmer water and it's supporting currents cause higher levels, cooler water and the supporting currents cause lower levels. In other words, this is an analog for seas surface temperatures.
