SWEDENWhat am I looking at?
MEPS is MetCoOp's 2.5 km HARMONIE-AROME run — the model SMHI, MET Norway and FMI operate together, and the one SMHI's own forecast starts from — every three hours to T+66, with the fields a phone app never shows: visibility, CAPE, radiation and the levels aloft. The radar is SMHI's own composite of eleven Swedish radars, every five minutes. ECMWF holds the ten-day synoptic outlook on a Europe frame, and the Baltic wave and sea models cover the water, from Skagerrak to Bottenviken.
Switching model holds the valid time, not the forecast hour, so flipping between MEPS and ECMWF — or MEPS and what the radar actually saw — shows a real disagreement between two pictures of the same instant, rather than an artefact of comparing two different moments on two different clocks.
Fields are drawn straight from the published output with no smoothing and no rescaling — colour ramps are pinned to absolute values, so a loop shows real intensity changes rather than a palette re-fitting itself each frame. Temperatures are Celsius and winds metres per second, the way SMHI states them. For warnings, smhi.se is always the authority.
