The wind map of the world
The wind is one of the most powerful forces in Nature. It has a violent, destructive strength, it creates swells, and it produces energy. Check how, when and where the wind is blowing.
Planet Earth has many famous winds, but they only exist and behave like they do due to:
1. The sun's energy - which does not heat up the Poles and the Equator evenly;
2. The Earth's rotation - which makes the ocean currents and the winds to move from east to west;
3. The Coriolis effect - which makes changes in wind direction;
3. The irregularities of the Earth's surface - which alter the direction, speed, and temperature of the wind;
Technological advances now make it possible to have real-time, interactive and sophisticated wind maps that instantly deliver easy-to-read variables such as wind speed, wind direction, and wind temperature.
Understanding how winds form - including their pattern, pressure, and temperature - allows us to make predictions and forecasts. Winds are responsible for the creation of swells and waves, but they are also behind the most violent storms.
Traditionally, the wind is measured in knots. The Beaufort Scale is an empirical measure for identifying wind speed based on observed sea conditions. The anemometer is a scientific device for accurately measuring wind intensity.
Winds are the result of pressure differences. An accurate, scientific wind map features several atmospheric variables, including:
1. Isobars: circular lines which represent the pressure difference (gradients);
2. Wind barbs: small little "keys" which indicate wind direction and wind speed;
3. Low-pressure center: designated by the letter "L";
4. High-pressure center: designated by the letter "H";
