potential evaporation उदाहरण वाक्य

The harsh climate of the Sahara is characterized by : extremely low, unreliable, highly erratic rainfall; extremely high sunshine duration values; high temperatures year-round; negligible rates of relative humidity; a significant diurnal temperature variation; and extremely high levels of potential evaporation which are the highest recorded worldwide.
During the late 1970s and 1980s and mid-1990s there were concerns that the water levels within the forest and within neighbouring Warren were falling due to a greater potential evaporation demand caused by afforestation, with the result that winter flooding was not to the same depth and that dune slack pools were drying out sooner.
