Evapotranspiration in an arid environment

Evapotranspiration is an important process in the water cycle because it is responsible for 15% of the atmosphere's water vapor. Without that input of water vapor, clouds could not form, and precipitation would never fall. It is the process by which water is transferred from the land to the atmosphere by evaporation from the soil and other surfaces and by transpiration from plants.

Urban land and aerosols amplify hazardous weather, steer storms toward cities

Urban landscapes and human-made aerosols—particles suspended in the atmosphere—have the potential to not only make gusts stronger and hail larger; they can also start storms sooner and even pull them toward cities, according to new research exploring the impact of urban development on hazardous weather, led by scientists at the U.S. Department of Energy's Pacific Northwest National Laboratory.

Error correction means California's future wetter winters may never come

California and other areas of the U.S. Southwest may see less future winter precipitation than previously projected by climate models. After probing a persistent error in widely used models, researchers at the Department of Energy's Pacific Northwest National Laboratory estimate that California will likely experience drier winters in the future than projected by some climate models, meaning...

The Guardian view on a Covid Christmas: better safe than sorry | Editorial

Easing of UK restrictions should not go ahead while they risk a third wave of coronavirus Christmas is on hold. The governments of the four nations of the United Kingdom are reviewing the proposed relaxation of their Covid restrictions over the holidays.
