Scientists better prepared to judge ash cloud

Scientists say they are now better prepared for measuring Iceland's volcanic ash problem, which is expected to continue for several months, after experiments using modelling and lasers to probe the atmosphere.

A new method to improve tropical cyclone intensity forecasts

In numerical weather forecasting research, how to improve short-term forecasts of tropical cyclone intensity is a challenging problem that has long plagued meteorologists and operational forecasters, despite that meteorologists ...

Atmospheric turbulence may promote cloud droplet formation

Clouds form when water vapor in moist packets of air condenses onto atmospheric aerosols, such as particles of dust. The transition from dry particle to liquid water droplet is known as activation. The threshold for activation ...

Detecting clouds from both sides now

Researchers have developed a more precise method to detect the boundary between clouds and clear air, by exploiting the swinging motions of a weather balloon and its payload.

A new metric to help understand Amazon rainforest precipitation

In the Amazon rainforest, the chain of events that turns a small-scale process like a localized increase in evaporation into a towering storm cloud is long and twisted. To understand the complex dynamics that lead to precipitation, ...
