<dd>This study was conducted to examine the effects of clouds on the ocean mixed layer, both short-term and seasonal. It utilized data collected at Ocean Station Papa in the northeast Pacific. Two numerical modeling simulations were performed (i.e., with variable cloud and with variable precipitation). The results for the variable cloud simulation indicated that the downward surface buoyancy flux and longer daylight period in summer may induce a significant albedo effect of cloud on ocean mixed layer. The upward surface buoyancy flux and longer night period in winter will result in a pronounced greenhouse effect of cloud on ocean mixed layer. The results of variable precipitation simulation showed that the mixed layer is most sensitive to precipitation between October and March. Model predictions are verified using data at Ocean Station Papa for monthly and yearly mean values of cloud cover and precipitation. The comparison between model prediction and observations shows that the mean values of observed MLD (H = 60.9 m) are much deeper than model-predicted values (H = 36.5 m)</dd></dl><br>Subjects:</div>
