Seasonal weather changes are really interesting and happen because of a few important reasons. Let’s take a closer look at what causes these changes:
One big reason we have different seasons is because the Earth is tilted. It leans about 23.5 degrees on its axis. This tilt means that different parts of the Earth get varying amounts of sunlight all year long.
When the Northern Hemisphere (the top half of the Earth) is tilted towards the sun, we enjoy summer. But when it tilts away, we experience winter. This cycle happens as the Earth travels around the sun, which takes about 365.25 days.
The strength and length of sunlight also change during the year. Near the equator, days are about the same length all year, so the temperatures don’t change much.
But in places farther away from the equator, like the UK, daylight can be very different in each season. For example, in summer, the sun stays out longer and shines more directly, making it warm. In winter, the days are shorter, and the sunlight isn't as strong, which makes it colder.
Air and weather systems are crucial in season changes. The Earth heats unevenly, creating different air pressure areas. This, in turn, causes wind patterns that can affect local weather.
Warm air rises near the equator, creating low pressure, while cooler air at the poles creates high pressure. These big wind patterns can bring changes in the weather, from sunny to rainy days.
Don't forget about the oceans! Ocean currents can greatly affect the weather near the coast. Warm currents, like the Gulf Stream, help keep winters mild along the west coast of Europe. On the other hand, cold currents can make nearby areas much cooler.
The way ocean water temperatures mix with atmospheric conditions can create complicated weather patterns and seasonal changes.
Lastly, local features, like mountains, valleys, and lakes, can change the weather in a region. Mountains can block air, leading to dry areas, while valleys may trap warm air, causing temperature differences.
So, two places close to each other can have very different weather because of their geography.
In summary, the changes in seasonal weather come from Earth’s tilt, how strong and long the sunlight is, wind patterns, ocean currents, and local geography. Understanding these reasons helps us see why the weather changes so much throughout the year!
