Cold-air outbreak (CAO) events in the mid-latitudes draw cold polar or continental air masses over a relatively warm ocean, resulting in a rapid increase in the surface fluxes of heat and moisture from the sea surface and the subsequent development of extensive boundary layer clouds.
The Infrared Atmospheric Sounding Interferometer (IASI) instruments, on board the MetOp-A and MetOp-B satellites (a third on MetOp-C should be launched in November 2018), are primarily meteorological instruments designed to provide accurate atmospheric temperature and humidity profiles with which to improve numerical weather prediction (NWP).
This new multi-million pound initiative will train the next generation of experts in the analysis of "big data" using advanced statistical methodologies and the latest cloud computing technologies, addressing an acute worldwide skills shortage.
Clouds have a major effect on the climate system. They interact with both solar radiation and terrestrial radiation, leading to changes in surface heating rates, moisture content, and large scale dynamics.
Ice particles in clouds play an important role for both weather and climate prediction. Half of all precipitation globally is initiated through the formation of ice, while the radiative impact of ice clouds is very important because of their widespread coverage.
