Abstract
The pilot‐balloon ascents for a period of ten years are analysed in order to study the sea breeze effect on upper winds from the surface to 5,500 feet. When sea breezes replace land breezes during the course of the day, the vector change in speed normal to the coast is in the order of 15 mi./hr. in the layer up to 500 feet and decreases with height to become negligible above about 5 m feet. The sea breeze has an average depth of 1,500 feet, but there is no evidence of an increased outflow to form a returning current up to the highest level considered. There is also an added component parallel to the coast of about 5 mi./hr. with the land to the left. When the sea breeze is continuous owing to a general current off the sea there is very little increase in the speed, but the wind definitely backs during the course of the day.
