Climatic Analyses
Weather anomalies
Weather anomalies refer to the deviation of current climate observations from a long-term average. This can be used to show, for example, how current monthly values compare to the current climate reference period (1991-2020).
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 the difference between the total precipitation and the sum of potential evapotranspiration according to FAO56 in a specific area. It is used as a measure to describe water availability and can provide insights into expected 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.
