The objective of the project has been to develop atailored weather-forecast-system for peat harvesting.The peat producers have used weather forecasts since1985. It has been recognized that the production isvery weather sensivite. The question was, how weatherinformation sensitive are the operations at the peatmoor?
The project has shown that there isa flexibility inthe operations and that the decisions and plannings bythe work leaders can and shall be adjusted to forecastweather. This adjustment leads mostly to betterresults in the amount of produced peat fuel and incosts in the production.
The forecast of precipitation is most essential. Thisforecast should be expressed as probability of rain.The thresholds should be one low value (1.o mm/timeunit)and one higher showing the risk of rain amountthat could stop the production more severely. A dryingindex shall also be forecast.
The best way for the dissemination of forecasts istoday by telefacsimile twice a day, one early in themorning for the decisions of the day and one in theearly afternoon for decisions for the night andplanning of the following days (up to 5 days).
There isa need fora development of the forecastquality.
The weather service at the Swedish Meteorological andHydrological Institute has capability of serving peatfuel production indifferent parts of Sweden. Newtools as remote sensing techniques (weather radar,weather satellites) and automatic weather stationsprovide better observational methods for short rangeforecasts. Methods for longer forecast are continouslyimproved. The dissemination and presentation offorecasts can be better adjusted to special needs.
The project was funded by the National Energy Administration,Sweden (Project No 216 067 Peat-Weather) andcontractor has been the Swedish Meteorological andHydrological Institute.
