The station and front notation of the Japanese chart.
Also known as: JMA chart symbols, Japanese weather map symbols
The symbol set used on Japan Meteorological Agency surface charts, close to the international convention and divergent in places.
Encodes observed weather on a Japanese surface chart.
Contexts: Public information, Maps
Uses a set of twenty-one weather glyphs in the school and broadcast form, fewer than the WMO's hundred present-weather codes; the reduced set is what a Japanese pupil learns to draw and is not the set the agency's own analysts use.
Contexts: Public information, Maps
A circle for each station with strokes and figures set around it for wind, cloud and pressure, and long lines with triangles or half-discs along them for fronts.
