Quick Summary

An invisible drought occurs during hot summers when high rates of evaporation and transpiration exceed the amount of water supplied by rainfall. This leads to a gradual reduction in water availability, even if precipitation occurs frequently. While not as dramatic as other drought types, this borderline water deficiency can diminish crop yields. Droughts, in general, happen when evaporation and transpiration consistently surpass precipitation over time, causing water shortages and impacting agriculture.12
