Why do some wind patterns stay in the same direction for months at a time?
Quick Answer
Large-scale pressure belts and temperature contrasts can persist seasonally, steering winds the same way for long periods. The position of the Sun and the land-sea contrast help lock in these patterns.
The Full Story
Wind direction is controlled by pressure differences, and some of those differences are seasonal and long-lasting. As the Sun shifts north and south over the year, pressure belts move too, and continents heat and cool in a predictable way. That is why monsoon winds, trade winds, and many regional wind systems can keep a consistent direction for weeks or months. Ocean temperatures, mountain ranges, and jet streams can reinforce the pattern and make it even more stable.
