A windy day is characterized by strong air movement, which can be felt as gusts or steady breezes. Wind is caused by differences in air pressure, often influenced by temperature changes and geographical features. On such days, trees sway, leaves rustle, and kites can soar high in the sky. Windy days can impact various activities. For example, outdoor sports may be affected, and people may need to secure loose items to prevent them from blowing away. Additionally, wind can play a role in weather patterns, influencing storms and temperature changes in the surrounding environment.
