Cooler air offshore is drawn in to replace the rising air inland, and a cool sea breeze develops. Usually, the effects of the sea breeze can be felt over only a few miles, but occasionally the air blows inland much further. At night, the land cools down quickly radiating heat to the atmosphere, whilst the sea remains relatively warmer. Under these conditions the sea breeze may reverse to form a land breeze. The presence of mountains can significantly influence the local climate.
Mountains force air to rise, and consequently assist the development of clouds and precipitation.
It is not uncommon for rain to be falling at the top of a mountain, whilst further downwind it may be dry and even sunny in the rain shadow. Cities contains a lot of concrete structures like streets and buildings which soak up sunlight during the day. At night, they release this heat, which warms urban areas several degrees Celsius above nearby rural areas. This phenomenon is known as the urban heat island effect.
