Introduction
Many elements influence a region’s day-to-day weather and long-term climate. Those closer to the equator or sea level are often warmer than areas at high heights or distant from the equator. Local geography, such as distance from the water and proximity to mountains, also has a significant impact. The kind of vegetation in a location can also considerably affect local weather climate patterns. The vegetation in a location can also significantly impact local weather patterns. Mountain ranges act as natural air-movement barriers. The Coastal Range permits condensation and mild precipitation.
What is Weather
What is the weather like? It is the collection of daily occurrences that occur in our atmosphere. Weather varies according to the area and can change in minutes, hours, days, and weeks.
Climate definition
Climate refers to the average weather in a particular location over a lengthy time. The average temperature, rainfall, and sunlight are all included in a climatic description. Climatic change is described as any long-term systematic change in long-term statistics of climatic variables like temperature, precipitation, pressure, or wind that lasts many decades or more.
Climate change may be driven by natural external influences (such as variations in solar output or changes in the Earth’s orbit and biological internal climate system processes) and human action.
Factors that affect weather and climate
Altitude
Usually, as altitude increases, climatic conditions grow colder.
Prevailing global wind patterns
The Northern Hemisphere has three primary wind patterns, while the Southern Hemisphere has three. These are average circumstances and do not always reflect conditions on a particular day. Wind patterns shift north or south as the season’s change. The intertropical convergence zone, which flows back and forth across the Equator, accomplishes the same. Because the winds in this area are typically light, sailors referred to it as the doldrums.
Angles and latitude of the sun’s beams As the Planet orbits the sun, the tilt of its axis produces variations in the angle at which the sun’s rays strike the earth, hence changing the length of daylight at various latitudes.
Topography
A region’s topography may have a considerable influence on our climate. Mountain ranges act as natural air-movement barriers. Winds of the Pacific Ocean push moisture-laden air toward the coast of California. The Coastal Range permits condensation and mild precipitation. The higher Sierra Nevada range in the interior circles more substantial rainfall in the air. Sinking air heats from compression over the Sierra Nevada’s western slopes, clouds dissipate, and dry conditions predominate.
Effects of Geography
The location of a town, city, or locality and its distance from mountains and large bodies of water influence its prevailing wind patterns and the air masses that impact it. When colder ocean air rushes onshore in the summer, coastal locations may experience soothing breezes. In the winter, areas south and east of the Great Lakes might anticipate “lake effect” snow when cold air passes over comparatively warmer seas.
In the spring and summer, residents of Tornado Alley in the central United States keep an eye out for thunderstorms caused by fluctuations that cause seasonal tornadoes.
The surface of the Earth
Simply looking at a globe or a global map that depicts land cover reveals another critical component that influences climate: the Earth’s surface. The quantity of sunlight absorbed or reflected by the surface impacts the amount of heating in the atmosphere. Darker areas, such as highly vegetated regions, are sound absorbers, whereas lighter areas, such as snow and ice-covered areas, are good reflectors. The water absorbs and releases heat at a slower rate than land.
Climate change over time
Cold and warm times have occurred throughout Earth’s lengthy history. Some were relatively brief, while others lasted hundreds of thousands of years. Glaciers formed and spread across enormous areas during specific frigid eras. The ice receded over consecutive warm spells. Each epoch had a significant impact on plant and animal life. The most recent chilly period, known as the “Little Ice Age,” ended approximately 1850 in Western Europe. Climate definition geography is not exact due to this.
Temperatures have been continuously rising over the planet since the twentieth century. However, it is unclear how much of this global warming is due to natural reasons and how much is due to human actions such as the use of fossil fuels and forest destruction.
