Coordinates: 36.8021143°N, 138.783589°E · Requested elevation: 882 m. Model terrain: 1109 m. Terrain and 1000/925/850/700 hPa profiles are used for height estimates.
Outside the available profile, temperature uses an estimated 5.5°C/km height correction; wind retains the nearest available model-level value. Humidity is estimated with adjusted pressure and temperature.
These are altitude estimates, not a simulation of local mountain terrain. Precipitation, cloud and sea-level pressure use horizontal interpolation only.
Precipitation includes rain and snow water equivalent: preceding 3 hours through day 6, then 6 hours (see cell tooltip). Snow (cm) estimates fresh snowfall from precipitation and temperature using the GFS conversion; it is not snow depth on the ground. Freezing (m) uses additional 600/500 hPa temperatures when available and estimates the lowest resolved 0°C crossing above sea level. When all sampled levels are warm, the upper profile limit is shown (see tooltip). < marks an entirely cold sampled profile and its lower height limit. No extrapolation is used.
