| Algorithm: | (link1) | The Sager Weathercaster is an instrument based on meteorological science and predicts the weather quickly and accurately. It has been in use since 1942. It allows you to make forecasts of weather, temperature and wind instantly for a radius of about 50 km of your location based on 5000 input variations. |
| Input: | (link2) | The Sager Weathercaster algorithm is provided with input from the private PWS via CMX webtags (wind direction and trend, pressure and trend) and input from a nearby METAR station via Curl (sky cloud cover (pw)). |
| 12-24h Zambretti Forecast: | zf | Changeable, Some Rain |
| Zambretti Output Code: | zoc/zfo | P (Letter A - Z with 26 options) = (Changeable, some rain)orig |
| Algorithm: | (Wiki) | The Zambretti Forecaster is a weather forecasting instrument used in conjunction with a barometer. It has been in use since 1915. |
| Input: | (link3) | The Zambretti Forecaster uses wind direction, pressure and a rising, falling or steady barometer based on the season (Spring/Summer/Fall/Winter) as input (3 dials). |
| Current Temperature: | tr/ts | 7.9 °C (to determine rain or snow) |
| Avg Wind Direction 6h ago: | b6/w6 | 141° SE |
| Current Avg Wind Direction: | bd/wd | 22° N |
| Wind Speed Unit: | wu | km/h |
| Wind Trend: | wdc | The wind is Backing. |
| Barometric Pressure: | bp | 987.6 |
| Pressure Trend: | bt | -0.0 |
| Pressure Unit: | bu | hPa |
| Pressure converted to [hpa]: | pc | 987.6 |
| Pressure Trend [hpa]: | pt | -0.0 (falling rapidly <= -1.4 < falling <= -0.7 < normal < 0.7 <= rising < 1.4 <= rising rapidly) |
| Pressure Offset Sager: | po | 0 (default = 0, set to +5/+10 if wind speed forecast is too high, set to -5/-10 if wind speed forecast is too low) |
| Pressure used Sager [hpa]: | pu1 | 987.6 (including offset (po)) |
| Pressure Offset Zambretti: | po2 | 18 (offset based on season offset 0 (so) + wind offset 18 (wo)) |
| Pressure used Zambretti [hpa]: | pu | 1005.6 (including offset (po2)) |
