How are winds typically reported in meteorological terms?

Winds are typically reported in meteorological terms based on the direction from which they originate, which is denoted as coming from a specific compass direction. For example, a wind reported as "from the east" signifies that the wind is blowing toward the west, with its origin being the east.

This convention is crucial for understanding how wind affects movement and navigation, especially in aviation, where pilots need to account for wind direction in their flight planning and operations. Knowing the wind's source allows pilots to adjust their heading and understand potential impacts on their flight path, including drift and fuel consumption.

Other methods of reporting wind, such as using speed in kilometers per hour or knots, or considering relative motion to the aircraft’s heading or barometric pressure changes, are not standard in meteorological reports. The primary focus on the direction from which winds come makes option B the correct answer, as it aligns with established meteorological practices.
