Directly or indirectly, the sun provides energy for living organisms, and it drives our planet’s weather and climate patterns. Because Earth is spherical, energy from the sun does not reach all areas with equal strength.
What causes weather patterns?
The local weather that impacts our daily lives results from large global patterns in the atmosphere caused by the interactions of solar radiation, Earth’s large ocean, diverse landscapes, and motion in space.
What factors influence climate patterns?
3.1 Factors affecting climate
- distance from the sea.
- ocean currents.
- direction of prevailing winds.
- shape of the land (known as ‘relief’ or ‘topography’)
- distance from the equator.
- the El Niño phenomenon.
What is a weather pattern?
A weather pattern occurs when the weather stays the same for days or weeks at a time. Some common weather patterns include hot and dry weather, wet and rainy weather, and cold weather. If weather patterns go on for too long, they can lead to emergencies like heat waves, flooding, and blizzards.
Where do weather patterns begin?
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. Warm air rises, and cold air then rushes in underneath to replace it. This movement of air is what we call wind.
Climate is the long-term average of the weather in a given place. While the weather can change in minutes or hours, a change in climate is something that develops over longer periods of decades to centuries.
What are the major controls of the climate?
There are six major controls of the climate of an area. These factors are latitude, elevation, nearby water, ocean currents, topography, vegetation, and prevailing winds.
How is climate and weather different?
Weather refers to short term atmospheric conditions while climate is the weather of a specific region averaged over a long period of time. Climate change refers to long-term changes.
What is a weather pattern and a pattern change?
It is common for the weather to become locked in a repeating pattern. The same weather will occur day after day. Then suddenly one day the weather changes and for example dry weather for 2 weeks becomes rainy weather for a week. When this happens it is referred to as a weather pattern change.
How do weather patterns develop?
Changes in atmospheric pressure create weather patterns, which we’ll discuss later on. High pressure areas bring calm, cool, sunny weather whereas low pressure areas bring warm weather, rain, and clouds. … Changes in air pressure also bring about clouds, collections of dust, and water vapor in the atmosphere.
How do weather patterns move?
The reason that they most often move from west to east is due to the jet stream. … Jet streams carry weather systems. Warmer tropical air blows toward the colder northern air. These winds shift west to east due to the rotation of the earth.
What are the components of weather patterns?
Weather is made up of six main components. These are temperature, atmospheric pressure, cloud formation, wind, humidity and rain. A small change to any of these conditions can create a different weather pattern. Every weather pattern has a knock-on effect, creating a ripple effect around the world.
