An Investigation of the Southern Ocean Surface Temperature Variability Using Long-Term Optimum Interpolation SST Data

Figure 3

Time series showing the variation of Southern Ocean surface temperature anomalies (in °C). Black line shows the mean anomaly, red line gives the maximum values, blue line, minimum, and the dashed lines represent ±sigma. Here, mean represents the average temperature anomaly over the entire region; minimum (maximum) is a value at a particular pixel with the lowest (highest) temperature; standard deviation represents the fluctuations around the mean over the entire period of study. A linear trend (green straight line) is also shown, with the regression statistics given at the top left corner.
