    Sea Land Breezes

    During the day, the land heats up faster than the water, causing warmer air over the land to rise and creating an area of low pressure. Meanwhile, the air over the ocean is cooler, forming a high pressure area. This pressure gradient causes the cooler air over the ocean to flow inland as a sea breeze. At night, the pattern reverses as the land cools faster than the water, becoming an area of high pressure. Winds then blow from the land to the ocean in the form of a land breeze.

    Sea & land breezes

    AS Geography
    Daytime development of sea breeze.
    ??
    • During the daytime land heats up much faster than water
    as it receives solar radiation from the sun.
    • The warmer air over the land then begins to expand and
    rise forming a thermal low. At the same time, the air over
    the ocean becomes a cool high because of water's
    slower rate of heating. Air begins to flow as soon as
    there is a difference in air temperature and pressure
    across the land to sea gradient. The development of this
    pressure gradient causes the heavier cooler air over the
    ocean to move toward the land and to replace the air
    rising in the thermal low. This localized air flow system is
    called a sea breeze
    Sea Breeze
    Night time development of land breeze
    ??
    • At sunset, the land surface stops receiving radiation from
    the sun.
    • As night continues the land surface begins losing heat
    energy at a much faster rate than the water surface.
    After a few hours, air temperature and pressure
    contrasts begin to develop between the land and ocean
    surfaces. The land surface being cooler than the water
    becomes a thermal high pressure area. The ocean
    becomes a warm thermal low. Wind flow now moves
    from the land to the open ocean. This type of localized
    air flow is called a land breeze.
