These results indicate that the Coriolis force may be more important than the reversal of horizontal temperature gradient from day to night in producing large-scale land-scale land breeze away from the equator. The results pertaining to the large-scale circulation are in general agreement with Rotunno's linear theory, which predicts a fundamentally different behavior of the sea-breeze circulation depending upon whether the Coriolis parameter is greater or less than the frequency of the diurnal heating cycle.

Recall that the land surface cools quicker than the water surface at night. Therefore, the warmer air over the ocean is buoyant and is rising. The denser cool air over the land is flowing offshore to replenish the buoyant warm air and is called a land breeze.

A secondary circulation is a circulation induced in a rotating system. With prevailing east winds, they actually help push the sea breeze front and thunderstorms as much as half way across the peninsula.

On smaller peninsulas, such as at the northern tip of New Zealand, sea breezes from opposite coasts may collide.

In these situations, two lines of thunderstorms may collide and combine into a single but intense, short-lived line. The opposite of a sea breeze is a land breeze. While sea breezes occur during the day, land breezes occur at night.

Despite the difference in times at which the land breezes and sea breezes occur, the reason for the land breeze's formation is basically the same as the sea breeze, but the role of the ocean and land is reversed. Land breezes can occur when the land's nighttime temperature is less than the sea surface temperature.

They are most common during the fall and winter seasons when water temperatures are still fairly warm and nights are cool. However, unlike the sea breeze, the land breeze is often much weaker. At night, the land temperature falls to below that of the ocean resulting in an increase in the air's density. Gravity's downward pull moves air downhill spilling it onto the water 1. This denser air undercuts the lighter, warmer air over the water 2 forcing it up into the atmosphere 3.

This rising air forms a weak low-pressure area 4. The rising air accumulates aloft forming an area of higher pressure 5.
