Scientists say a circumhorizontal arc is an optical phenomenon - an ice-halo formed by plate-shaped ice crystals in high level cirrus clouds
Although the flat plates make up the smallest fraction of particles in a cirrus cloud
, if they align in similar directions they can have a strong influence on how much radiation the cloud blocks, says Liou.
Identifying cirrus cloud
locations--and the details of how any given cloud formed, something that was difficult to do before--is very important to understanding their contribution to global temperatures.
The effect is caused by the sun shining through ice particles in cirrus cloud
, after it's gone behind the horizon.
They can also act as a catalyst for the formation of further wispy cirrus cloud
The imaging infrared radiometer operates continuously, providing information on cirrus cloud
particle size and infrared emissions activity.
Fu and her colleagues counter with evidence that sea surface temperatures do not control cirrus cloud
The new data could be used to improve models of cirrus cloud
formation, the researchers say.
Warmer sea temperatures in the tropics cause changes in the relative distribution of cumulus and cirrus cloud
cover which allows heat to escape, helping to cool the planet.
A sample of the high upper turbulence associated with a cold front could be seen as cirrus cloud
earlier in the week.
storage is based on RAID 6 and 10, and is synced onto failover storage units, providing HA cloud storage to hypervisors as well as Vituozzo cores.
The jet stream is powering through at 220mph some 28,500 feet above us and it is pushing cirrus clouds
Haloes - rings that form around the sun or moon - are created by light being reflected by ice crystals formed in high cirrus clouds
are thin, wispy, and high in the sky.
HOW TO BECOME A WEATHER DETECTOR FIRST learn to recognise your clouds - cirrus clouds
are white, thin and wispy and form very high in the sky.
