19) draw the wind pattern that develops during the day during a sea breeze.

Figure given for reference.

Explanation:

The sea breeze is a circulation pattern that develops over the land and sea, due to differential heating and cooling of the land by the sun rays which cause the cool winds from the sea to enter the landscape in order to cool it. The reverse is a breeze blowing from land to sea when the oceans are warmed up the sun at night. These are important factors of prevailing winds systems. And the issue can be related to the convection current case at the equatorial zone of low pressure. These weather patterns continue to prevail for a period of 12 to 24 hours of the day.
