The station model uses a wind barb to show both wind direction and speed. The wind barb shows the speed using "flags" on the end. Each half of a flag depicts 5 kn (9.3 km/h; 5.8 mph) Each full flag depicts 10 kn (19 km/h; 12 mph) Each pennant (filled triangle) depicts 50 kn (93 km/h; 58 mph) [4]
The Romans (e.g. Seneca, Pliny) adopted the Greek 12-wind system, and replaced its names with Latin equivalents, e.g. Septentrio, Subsolanus, Auster, Favonius, etc. The De architectura of the Roman architect Vitruvius describes 24 winds.

Present weather symbols used on weather maps Wind barb interpretation A station model is a symbolic illustration showing the weather occurring at a given reporting station . Meteorologists created the station model to plot a number of weather elements in a small space on weather maps.

Describing a collection of low-lying, radially structured clouds with distinct shapes (resembling leaves or wheels in satellite imagery), and typically organized in extensive mesoscale fields over marine environments. They are closely related to and sometimes considered a variant of stratocumulus clouds. actinometer A scientific instrument used to measure the heating power of ...
