How ocean currents have an impact on rainfall?
4 min read
Asked by: Jim Bahraini
Ocean currents, and ocean water in general, can lead to atmospheric instability. As the water from the ocean evaporates, it turns into water vapor. This water vapor increases the temperature and humidity of the air, leading to precipitation and storms. In fact, nearly all rain originates from the ocean.
Does rainfall affect current?
These first-of-their-kind field observations indicate that rain reduces ocean wave form drag in favor of tangential stress, resulting in the acceleration of current near the sea surface.
How does cold currents affect rainfall?
Unlike warm currents, cold currents do not give rise to moisture laden winds and hence there is no rainfall in the coastal areas. These currents give rise to conditions which are the cause of desertification in the affected coastal areas.
Do warm ocean currents cause rain?
This warm water in the western Pacific Ocean causes low air pressure and high rainfall. (Warmer water causes the air above the ocean’s surface to warm and rise, leaving an area of lower pressure. More rainfall is associated with lower air pressure.)
How do ocean currents help in bringing rain in the land masses?
When water molecules are heated, they exchange freely with the air in a process called evaporation. Ocean water is constantly evaporating, increasing the temperature and humidity of the surrounding air to form rain and storms that are then carried by trade winds, often vast distances.
What causes rainfall changes?
Warmer oceans increase the amount of water that evaporates into the air. When more moisture-laden air moves over land or converges into a storm system, it can produce more intense precipitation—for example, heavier rain and snow storms.
What are effects of ocean currents?
Effects of Ocean Currents
- They result in rain. Warm currents lead to evaporation, which turns into the rain for the coastal areas. …
- They can also cause deserts. …
- They can destroy marine wildlife. …
- They help with the continuity of life. …
- They save up on time and costs. …
- They can result in deaths.
How does an ocean currents influence the rainfall distribution class 7?
1. The ocean currents carry cold water from the polar regions to equatorial regions. 2. The winds blowing over warm currents are moisture-laden and, thus, cause rainfall in the coastal areas.
How does the ocean affect the weather?
The ocean warms and cools more slowly than the atmosphere, thus coastal weather tends to be more moderate than continental weather, with fewer hot and cold extremes. Evaporation from the ocean, especially in the tropics, creates most rain clouds, influencing the location of wet and dry zones on land.
What is the role of ocean currents in maintaining the weather conditions?
Ocean currents bring warm water and rain from the equator to the poles and cold water from the poles toward the equator. These ocean currents help to counteract the high levels of solar radiation that the Earth’s equator receive.
Why are the ocean currents important?
By moving heat from the equator toward the poles, ocean currents play an important role in controlling the climate. Ocean currents are also critically important to sea life. They carry nutrients and food to organisms that live permanently attached in one place, and carry reproductive cells and ocean life to new places.
How do ocean currents affect climate quizlet?
A warm ocean current that flows toward the poles results in warm air masses that move over land that the current flows past. This causes the climate of that land area to be warmer than it would be otherwise. A cold ocean current that flows toward the equator results in cold air masses affecting the nearby land.
How do ocean currents affect climate Quizizz?
Cold currents result in cooler air temperatures, which speed up the rates of evaporation. Cold currents result in warmer air temperatures, which speed up the rates of evaporation. Warm currents result in cooler air temperatures, which slow down the rates of evaporation.
How do ocean currents affect the climate of coastal regions?
In coastal regions, cooler ocean currents tend to cause cooler land temperatures, and warmer ocean currents tend to cause warmer land temperatures in coastal regions.
