Pollen not only plays a role in allergies, but also influences the local weather. Especially in spring, when large amounts are released, it contributes to the formation of ice in clouds, which can ...

Atmospheric aerosol particles are essential for forming clouds and precipitation, thereby influencing Earth’s energy budget, water cycle and climate on regional and global scales. However, the origin ...

Oscillations are one of the intrinsic features of many animate and inanimate systems. The oscillations manifest in the temporal periodic change of one or several physical quantities describing the ...

Precipitation comes in all forms: rain, sleet, freezing rain, and snow. Some even count virga, which becomes a gas and evaporates before it reaches us as raindrops. Hail also exists but forms ...

In research that could improve weather forecasting and winter driving safety, a University of Michigan-led study distinguished nine distinct precipitation types—varieties of rain, snow and mixed-phase ...

Ground-based and satellite observations in the United States show that increased pollen concentrations in spring lead to more cloud ice and more precipitation—even at temperatures between minus 15 and ...
