Climatic Analyses ​

Weather anomalies ​

Deviations of current climatic measurements from the long-term average of the current climate reference period 1991-2020. The graphic display allows for quick identification of positive or negative trends.

Selection ​

  • Plot (sample area)
  • Variables:
  • Precipitation (precipAnomalies): Measured monthly precipitation and (in brackets) the difference between the measured precipitation and the average monthly precipitation in the reference period.
  • Temperature (tempAnomalies): Measured monthly mean temperature and (in brackets) the difference between the measured temperature and the monthly mean in the reference period.

Representation ​

  • Precipitation: Bars (blue) above or below the zero line.
  • Temperature: Line (red) above or below the zero line.
  • Functions: Zoom in and out and shift the time section, export as PNG (selected period) and CSV (entire data set).

Usecases ​

  • Climatic trend analysis over months and years.
  • Identification of extreme events (drought, heavy precipitation, heat waves).
  • Comparison of different sample areas.

In short: Weather anomalies provide a quick overview of deviations in current climate data from the long-term average.

Climatic water balance ​

The climatic water balance is a measure of the water supply in an area, calculated as the difference between total precipitation and potential evapotranspiration (FAO56). It provides information about the availability of water for vegetation.

Selection ​

  • Plot (sample area)
  • Variable:
  • Climatic water balance (cwbData): Difference between monthly precipitation total and potential evapotranspiration according to FAO56.

Representation ​

  • Mean value: Difference between the mean values of the monthly precipitation total and potential evapotranspiration.
  • Minimum/maximum value: Difference between the minimum and maximum values of the monthly precipitation total and potential evapotranspiration.
  • Standard deviation: +-1σ of the difference between the monthly precipitation total and potential evapotranspiration.
  • Annual progression of the current, last and penultimate year.
  • Functions: Export as PNG and CSV.

Usecases ​

  • Analysis of water availability for vegetation.
  • Evaluation of dry and wet periods.
  • Support for silvicultural decisions.
  • Comparison of different sample areas.

In short: The climatic water balance helps to analyse the water availability in an area and evaluate its effects on vegetation.
