It has been suggested that homogeneous freezing is the dominant pathway for cirrus cloud formation (Karcher and Strom 2003).
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.
When I walked out that spring day, a solitary cirrus cloud floated in front of me in an extremely deep-blue sky.
ACCRI has contributed to the estimation of aviation-induced cirrus cloud climate forcing based on global observation datasets and increased the level of scientific understanding from "very low" to "low.
Figure 4 shows some examples of spectra acquired in clear and cloudy sky (top panel), for a cirrus cloud, and for a low-level thick cloud, as well as the typical noise performances (bottom panel) over the full instrumental spectral range.
Fu and her colleagues counter with evidence that sea surface temperatures do not control cirrus cloud formation.
I assumed that this bar hid the rest of an upward Sun pillar that was being formed in higher-altitude cirrus cloud.
It is based on a Fourier Transfor Spectrometer to fill a long-standing observation gap of spectral observations from space in the Far InfraRed (FIR) region from 15 to 100 m with the aim to improve our understanding of climate relevant processes that are active in the FIR such as the water vapour greenhouseeffect the cirrus cloud greenhouse effect and the surface emission in high latitude and high altitude regions and to provide complementary information on the upper tropospheric/lower stratospheric (UTLS) water vapour and temperature profile retrievals comparedto the mid infrared.
We realize that the ARM cloud radar simulator can only provide a partial evaluation of model performance in simulating clouds given the limitations of cloud radars, such as their inability to detect small cirrus cloud particles that leads to underestimation of cloud-top height of high thin cirrus clouds.
For the time being, cirrus cloud thinning should be viewed as a thought experiment that is helping to understand cirrus cloud6formation mechanisms," the article says.
