Mapping the effects of drought on child stunting, Proceedings of the National Academy of Sciences (2019). Newly produced cells would be twice their normal size. 9 Easy April Fools' Pranks for Kids That'll Get Everyone Laughing. When the distribution of precipitation occurs more in the summer than in the winter, a lot of the water is quickly lost to evaporation and runoff, rather than being stored as snowpack. When the demand for water is high during a period of low rainfall, when the rivers and groundwater are not re-charged as usual, the impacts can be worse. Forests lose water through evapo-transpiration which feeds the local water cycle. Drought can be defined as a period of time when a geographical region or area experiences lower precipitation and drier than normal astmospheric conditions that causes water shortage. This gives rise to air currents that move moisture around the atmosphere and result in different patterns of rainfall in different regions.
