õhusuund

Õhusuund, also known as wind direction, refers to the compass point from which the wind originates at a specific location and time. It is a key meteorological parameter used in weather forecasting, navigation, aviation, and environmental monitoring. The understanding and measurement of õhusuund are essential for assessing weather patterns, planning aviation routes, and studying climate conditions.

The most common method of expressing õhusuund is by using compass points, such as north (0°), east (90°), south (180°), and west (270°). Intermediate points like northeast or southwest are also used for greater precision. Wind direction is typically measured using an anemometer combined with a wind vane, which indicates the direction from which the wind blows. Modern instruments provide digital data for accurate and real-time monitoring.

In meteorology, õhusuund is analyzed alongside wind speed to understand atmospheric movements. Variations in wind direction can indicate weather fronts, pressure systems, or local geographic influences. For example, a change in wind direction from land to sea can signal approaching storms or shifts in weather patterns.

In Estonia and other regions, monitoring õhusuund plays a vital role in environmental assessments and renewable energy planning, particularly in the optimization of wind power generation. Knowledge of prevailing wind directions helps in siting wind turbines and assessing their potential energy output.

Overall, õhusuund is a fundamental element in understanding atmospheric behavior and supporting various practical applications related to weather, climate, and environmental management.
