Factors that Determine Weather

The weather can be aptly described as a set of all existing phenomena that is contained in a particular atmosphere at any given time.

This terms usually pertains to the different activities of these phenomena over brief periods of time such as days or maybe even hours.

This is not synonymous to the term "climate" which essentially refers to the average atmospheric condition in a given place over a long period of time. When the term "weather" is used, it is understood to be the weather of the "Earth" as used collectively for the planet.

The different weather patterns most often come from the different temperature difference that can be observed from one place to another. If you will look at it from a large-scale point of view, the temperature differences exist simply because areas closer to the equator receive more energy per unit area from the Sun since it is closer to it compared to the poles.

If you look at the weather from a local point of view, you’ll be able to observe that the different surfaces have varying physical characteristics which contribute to the reflectivity, roughness or moisture content of the environment. Examples of these typical surfaces are ice sheets, forests, man-made objects and oceans.

These affect the weather locally simply because they are able to filter away sunlight, moisture and air or let these elements pass through unabated. That is why the humidity of forests compared to a shoreline is much lesser simply because of the ability of the canopy to shield away the sun.

There are other factors that lead to these differences and must be taken into consideration if one would go down to the local area of the weather.

Surface temperature also has a different way of influencing pressure differences. If you have a hot surface, it will naturally heat the air above it. It will further expand and lower the air pressure.

The consequential horizontal pressure gradient then accelerates the air from a high pressure to a low pressure, thus creating the effect of wind. And because of the Earth’s rotation, this wind then causes the curvature of the flow via the Coriolis effect.

There is so much more to explore about the weather. We have not even touched the topic of global warming or coastal breezes and seasons. The topic of weather is much too broad to be contained in one meager sitting and so it is up to the inquisitive mind of the reader to learn more about what he or she can about what influences the weather in our planet.
