What happens when trade winds stop?

What happens when trade winds stop?

The weakened trade winds allow warmer water from the western Pacific to surge eastward, so the sea level flattens out. This leads to a build up of warm surface water and a sinking of the thermocline in the eastern Pacific.

How do trade winds affect Hawaii?

The winds are changing over the Hawaiian Islands: There are fewer days with northeast trade winds than 40 years ago, a new study finds. Because the trade winds bring rain and clear out volcanic smog, the change could mean more drought and more hazy days for the island chain, the researchers report.

What are the effects of trade winds?

Trade winds have a big influence on the climate to the north and to the south of the equator. The main effects are: Continuous removal of humidity from the areas around the tropics = desertification. Continuous supply of humidity to the equator region = rain forest.

Do trade winds weaken?

Trade winds that sweep around half the globe are weakening as global warming disrupts normal atmospheric circulation, scientists report today. The winds, which bring rains to the west and churn up the oceans, turning surface waters into rich feeding grounds, cover 20,000km to drive weather conditions around the world.

What are trade winds Hawaii?

The islands of Hawaii are affected by the trade winds. These winds blow NE to ENE and are typically more prevalent in the winter months. These trade winds bring cool air to the islands from the north, often resulting in precipitation along inland/mountain and windward areas.

How does global warming affect trade winds?

The warm surface temperature is associated with reversed air pressure patterns and decreasing strength of trade winds, so more water stays in the eastern Pacific off the coast of South America.

What causes trade winds in Hawaii?

What are the trade winds?

These winds, which blow from a NE to ENE direction, became known as trade winds hundreds of years ago when trade ships carrying cargo depended on these easterly winds around the earth in the subtropics for speedy passage. During the summer, trades prevail more than 90\% of the time, sometimes persisting throughout an entire month.
