METEOROLOGY – CLIMATE CHANGE & PROJECTION CALCULATOR
Drought Probability Future
A precise tool.
What is the Drought Probability Future & How does it work?
Drought probability is influenced by changes in temperature and potential evapotranspiration (PET). As temperatures rise, PET increases, leading to higher water demand from plants and potentially exacerbating drought conditions.
The relationship between future drought probability and warming can be modeled using the formula: [ P_{drought} = f(T, PET) ] where ( P_{drought} ) is the probability of drought, ( T ) represents temperature changes, and ( PET ) is potential evapotranspiration.
P_{drought} = frac{T – T_{base}}{T_{max} – T_{base}} times (1 – frac{PET}{PET_{max}})
P_{drought} = Drought Probability, T = Temperature Change, T_{base} = Base Temperature, T_{max} = Maximum Temperature, PET = Potential Evapotranspiration, PET_{max} = Maximum PET

Frequently Asked Questions
How does temperature affect drought probability?
As temperatures rise, potential evapotranspiration increases, leading to higher water demand from plants and potentially exacerbating drought conditions.
What is potential evapotranspiration (PET)?
Potential evapotranspiration is the amount of water that would evaporate or transpire if there were no limitations such as lack of soil moisture or plant cover.
How do I use this calculator?
Input the temperature changes and potential evapotranspiration values into the formula to calculate the probability of drought.
What factors can influence PET besides temperature?
Factors such as humidity, wind speed, solar radiation, and plant type can also influence potential evapotranspiration.
How does this calculator help in planning for future droughts?
By understanding the relationship between temperature changes and PET, planners can better anticipate and prepare for potential drought conditions.
Can this calculator predict actual drought events?
While it provides a probability estimate, it does not predict specific drought events. It helps in assessing the likelihood of drought conditions under given climatic changes.
What is the formula used in this calculator?
The formula used is P_drought = f(T, PET), where P_drought is the probability of drought, T represents temperature changes, and PET is potential evapotranspiration.
