How do currents affect weather?
Ocean currents act much like a conveyer belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.
Why is convection an important factor in influencing weather?
Why is convection an important factor in influencing weather? They rise transporting heat and moisture into the atmosphere. The convection stretches higher into the atmosphere and is stronger in direct correlation with how hot the surface heating is.
How do air currents affect climate?
Air Currents Prevailing winds bring air from one type of climate to another. For example, warm winds that travel over water tend to collect moisture as they travel; the water vapor in the air will condense as it moves into colder climates, which is why temperate coastal areas often receive heavy rainfall.
How do air and ocean currents affect weather and climate?
They move water at temperatures at odds with the air above. This displaced water affects the air, by warming or cooling it. Thereby transferring the same effect to the land when the air blows across it. This is how ocean currents affect climate.
What does convection mean in weather?
transport of heat and moisture Convection. Generally, transport of heat and moisture by the movement of a fluid. In meteorology, the term is used specifically to describe vertical transport of heat and moisture in the atmosphere, especially by updrafts and downdrafts in an unstable atmosphere.
How are convection currents involved in Earth’s weather and climate?
Some currents are caused by convection, while others, called surface currents, are driven by wind. These currents move water all around the earth, bringing warm water to cooler areas and vice versa. This redistributes thermal energy and causes changes in the weather.
How do cold currents affect climate?
Warm and cold ocean currents can affect the climate of coastal regions, but only when local winds blow in from the sea. Warm currents heat the air over the ocean and bring higher temperatures over land. Cold currents can lower air temperatures and can bring colder temperatures over land.
How do changes in wind currents affect the short term climate?
How do changes in wind currents affect the short-term climate in a region? Prevailing winds can cause a milder climate with heavy rain. Global winds can cause a longer summer. Prevailing winds can cause heavy rains or a dry climate.
How does ocean convection affect the earth?
Some currents are caused by convection, while others, called surface currents, are driven by wind. These currents move water all around the earth, bringing warm water to cooler areas and vice versa. This redistributes thermal energy and causes changes in the weather.
How do convection currents affect the ocean currents?
Ocean Convection Convection drives the Gulf Stream and other currents that turn over and mix up the waters in the world's oceans. Cold polar water is drawn down from higher latitudes and sinks to the ocean bottom, pulled down toward the equator as lighter, warmer water rises to the ocean's surface.
What causes the weather?
Weather on Earth is caused by heat from the sun and movement of the air. All weather happens in the lower layer of Earth's atmosphere, which is a layer of gases surrounding Earth. The sun's heat warms the air in this layer to different temperature levels in different places.
Do convection currents cause thunderstorms?
The up and down motions associated with convection help fuel monstrous thunderstorms. A thunderstorm feeds off of warm air underneath it. Warm air near the ground rises because it's less dense.
Why do convection currents lead to rain?
Convectional rainfall occurs when surface of the earth is heated up by the sun. The warm surface also heats up the air. As air rises it cools down and begins to condensate. Further rising and cooling causes a large amount of condensation to occur and rain is formed.
Which type of currents affect climate?
The global conveyor belt's circulation is the result of two simultaneous processes: warm surface currents carrying less dense water away from the Equator toward the poles, and cold deep ocean currents carrying denser water away from the poles toward the Equator.
How does wind affect the weather?
Wind is a major factor in determining weather and climate. Wind carries heat, moisture, pollutants, and pollen to new areas. Many daily weather patterns depend on wind. A coastal region, for instance, undergoes changes in wind direction daily.
What causes windy weather?
The Short Answer: Gases move from high-pressure areas to low-pressure areas. And the bigger the difference between the pressures, the faster the air will move from the high to the low pressure. That rush of air is the wind we experience.
How do oceans influence weather and climate?
The oceans influence climate by absorbing solar radiation and releasing heat needed to drive the atmospheric circulation, by releasing aerosols that influence cloud cover, by emitting most of the water that falls on land as rain, by absorbing carbon dioxide from the atmosphere and storing it for years to millions of …
How do convection currents transfer heat into the atmosphere?
As the rock's temperature rises due to conduction, heat energy is released into the atmosphere, forming a bubble of air which is warmer than the surrounding air. This bubble of air rises into the atmosphere. As it rises, the bubble cools with the heat contained in the bubble moving into the atmosphere.
How do convection currents affect Earth’s atmosphere cold vs warm air )?
These convection currents create the Earth's oceanic winds: Warm air rises and spreads out in the upper layers of the atmosphere. As the air spreads out, it cools. Cool air sinks back to Earth's surface.
What affects the weather?
Weather conditions are determined by six major factors: air temperature, air pressure, humidity of the air, amount and kind of cloud cover, amount and kind of precipitation, and speed and direction of the wind.
What are the two main causes of weather?
Weather occurs primarily due to air pressure, temperature and moisture differences between one place to another. These differences can occur due to the sun angle at any particular spot, which varies by latitude from the tropics.
What is a convection in weather?
Convection. Generally, transport of heat and moisture by the movement of a fluid. In meteorology, the term is used specifically to describe vertical transport of heat and moisture in the atmosphere, especially by updrafts and downdrafts in an unstable atmosphere.
What is a convective weather event?
Convective storms or Thunderstorms, as they are more commonly referred to in the UK, are severe local storms associated with thunder, lightning, heavy rain, hail, strong winds and sudden changes in temperature. They can occur all year round but are most common during the summer months.
What causes rainfall?
Rain is liquid precipitation: water falling from the sky. Raindrops fall to Earth when clouds become saturated, or filled, with water droplets. Millions of water droplets bump into each other as they gather in a cloud. When a small water droplet bumps into a bigger one, it condenses, or combines, with the larger one.
What is convection rain fall?
Convectional rainfall occurs when the energy of the sun (or insolation) heats the earth's surface and causes water to evaporate changing to water vapor. This warm, moist air then rises, and as it rises, it cools.
What are kindergarten winds?

Why is foggy?
Fog will form when air is cold to its dew-point temperature, reaching what's called saturation. Cooler air can't hold as much water vapor as warm air, so once the air reaches that saturation limit, the water vapor will begin to condense out of it into the fog you can see.
Does the ocean influence our weather or climate?
The ocean is a significant influence on Earth's weather and climate. The ocean covers 70% of the global surface. This great reservoir continuously exchanges heat, moisture, and carbon with the atmosphere, driving our weather patterns and influencing the slow, subtle changes in our climate.
How does wind currents affect climate?
Air Currents Prevailing winds bring air from one type of climate to another. For example, warm winds that travel over water tend to collect moisture as they travel; the water vapor in the air will condense as it moves into colder climates, which is why temperate coastal areas often receive heavy rainfall.
How does convection affect the temperature of the Earth?
Convection is a vital process which helps to redistribute energy away from hotter areas to cooler areas of the Earth, aiding temperature circulation and reducing sharp temperature differences.
