a)

warmer than San Luis Obispo. The winds push ocean water that turns and follows the coasts. Energy is transferred from the ocean to the air at Isumi and energy is transferred from the air to the ocean at San Luis Obispo.

b)

warmer than San Luis Obispo. The winds push ocean water that turns and follows the coasts. A lot of energy is transferred from the ocean to the air at Isumi; only a little energy is transferred from the ocean to the air at San Luis Obispo.
