Flatau, "The relevance of the microphysical and radiative properties of
cirrus clouds to climate and climatic feedback," Journal of the Atmospheric Sciences, vol.
Atmospheric scientists have known that when compounds such as sulfates dissolve in water droplets, those tiny airborne solutions can freeze and create
cirrus clouds. Also, scientists have known that dust particles can serve as airborne platforms on which vapor freezes.
Another the natural
cirrus cloud coverage ([b.sub.cirrus]) from contrail parameterization in ECHAM4 is also given by (Sudqvist et al., 1989) the following:
How
cirrus cloud properties and occurrence rates may respond, however, is an equally compelling question to monitor in coming years compared with such newsworthy instances.
A
cirrus cloud's ice particles come in several shapes, says Liou.
When
cirrus clouds contain ice crystals with the proper orientation, a pair of these parhelia (Greek for "beside the Sun") can appear 22[degrees] or more to either side of the Sun, sometimes on a sky-circling band called the parhelic circle.
Using backward trajectory modeling, ML-CIRRUS shows that the climatic import of a given
cirrus cloud varies not just because some cirrus are manmade (contrails) and some are not.
They can also act as a catalyst for the formation of further wispy
cirrus cloud.
The development of
cirrus cloud forecast products based upon operational forecasts from the European Centre for Medium-Range Weather Forecasts (ECMWF) was essential to direct the aircraft into selected
cirrus cloud systems.
Multiple vertical profiles were executed through the outflow
cirrus cloud emanating from the cyclone.
