Seasonal changes have a big impact on the weather in many places around the world. These changes happen mainly because of how the Earth tilts and moves around the Sun.
Temperature Changes: As the Earth goes around the Sun, different areas get different amounts of sunlight. This causes changes in temperature throughout the seasons. For example, during summer (from June to August in the Northern Hemisphere), temperatures can be between 20°C and 30°C. In winter (from December to February), temperatures can drop to as low as -30°C in the polar regions.
Rainfall Patterns: Seasons also change how much rain falls in different areas. In tropical regions, there's something called the Intertropical Convergence Zone (ITCZ) that moves with the seasons. This creates wet and dry seasons. For example, in West Africa, the wet season can bring over 800 mm of rain each month, while the dry season might have less than 10 mm. In places like the Mediterranean, summers are dry and winters are wet, with average annual rainfall between 500 mm and 1,000 mm.
Storm Activity: Changes in the seasons can make storms stronger and more frequent. Tropical cyclones, which often happen between June and November, make up over 95% of hurricane activity in the Atlantic. These storms can produce winds faster than 74 mph and can cause a lot of damage, like Hurricane Katrina, which cost more than $125 billion in damages.
Effects on Nature and Farming: The changes in weather due to seasons also affect farming. For example, in temperate areas, how well crops grow is closely linked to the average temperatures during different seasons.
In conclusion, seasonal changes play a critical role in shaping the weather around the world. They affect temperature, rainfall, storm activity, and nature, which are all important for understanding our planet's climate.
