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 ...

As part of the international CLOUD project at the nuclear research center CERN, researchers at PSI have identified so-called sesquiterpenes—gaseous hydrocarbons that are released by plants—as being a ...

Graduate students analyze cloud formation data with research scientist Jesse Anderson, using the Pi Cloud Chamber to study atmospheric processes. × Michigan Tech's Pi Cloud Chamber is giving ...

Every year between September and December, Lubna Dada makes clouds. Dada, an atmospheric scientist, convenes with dozens of her colleagues to run experiments in a 7,000-gallon stainless steel chamber ...

Using 35 years of satellite data, researchers observed a consistent pattern for ice cloud formation stemming from desert dust in the atmosphere. The way clouds freeze is vital piece of the puzzle for ...

A cloud simulation that captures the development and evolution of clouds based on atmospheric physical processes is more accurate than other models. "Our model describes atmospheric conditions and ...

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 ...
