Local and Planetary Winds
Local winds are winds that affect a small area and change over short periods, while planetary winds are large-scale wind belts formed by global pressure patterns and Earth’s rotation.
Practice This ConceptMain explanation
Teacher explanation
Sea breeze and land breeze are local winds caused by different heating rates of land and water. Planetary winds such as trade winds and westerlies are part of global circulation and affect large regions for long periods.
Example
During daytime near a coast, sea breeze blows from sea to land; at night, land breeze often blows from land to sea.
Simple analogy
Sea breeze comes from sea; land breeze comes from land.
Common confusion
Students often interchange sea breeze and land breeze directions. Sea breeze occurs when land is warmer in the day; land breeze occurs when land cools faster at night.
Exam tip
For breeze questions, first identify day or night, then decide which surface is warmer and where low pressure forms.
