Research of the Distribution Characteristics and Generation Mechanism of Cirrus Clouds over the Qinghai-Xizang Plateau in Summer

open access: yesGaoyuan qixiang, 2023
Cirrus clouds play a significant role in Earth's energy balance and in the hydrological cycle of the atmosphere.In this study, we focus on the period of several years, 2007 to 2010, and the area, the Qinghai-Xizang Plateau, to analyze the generation ...

Shallow cirrus convection – a source for ice supersaturation [PDF]

open access: yesTellus: Series A, Dynamic Meteorology and Oceanography, 2014
The origin and persistence of high ice supersaturation is still not well understood. In this study, the impact of local dynamics as source for ice supersaturation inside cirrus clouds is investigated.

Cirrus cloud retrieval with MSG/SEVIRI using artificial neural networks [PDF]

open access: yesAtmospheric Measurement Techniques, 2017
Cirrus clouds play an important role in climate as they tend to warm the Earth–atmosphere system. Nevertheless their physical properties remain one of the largest sources of uncertainty in atmospheric research.

The Role of Global Thunderstorm Activity in Modulating Global Cirrus Clouds

open access: yesGeophysical Research Letters, 2023
Cirrus clouds provide a significant radiative forcing on the Earth's climate system. This paper looks at the connection in space and time between monthly mean lightning activity observed from the Lightning Imaging Sensor on board the International Space ...

Optical and geometrical properties of cirrus clouds in Amazonia derived from 1 year of ground-based lidar measurements [PDF]

open access: yesAtmospheric Chemistry and Physics, 2017
Cirrus clouds cover a large fraction of tropical latitudes and play an important role in Earth's radiation budget. Their optical properties, altitude, vertical and horizontal coverage control their radiative forcing, and hence detailed cirrus ...

Observation of cirrus clouds with GLORIA during the WISE campaign: detection methods and cirrus characterization [PDF]

open access: yesAtmospheric Measurement Techniques, 2021
Cirrus clouds contribute to the general radiation budget of the Earth and play an important role in climate projections. Of special interest are optically thin cirrus clouds close to the tropopause due to the fact that their impact is not yet well ...

The effect of optically thin cirrus clouds on solar radiation in Camagüey, Cuba [PDF]

open access: yesAtmospheric Chemistry and Physics, 2011
The effect of optically thin cirrus clouds on solar radiation is analyzed by numerical simulation, using lidar measurements of cirrus conducted at Camagüey, Cuba. Sign and amplitude of the cirrus clouds effect on solar radiation is evaluated.

Search for Man-Made Cirrus Contrails over Southeast Asia

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2007
In this study we examine the effect of natural perturbations on cirrus cloud cover in the tropics and we look for possible signal of cirrus contrails in tropical air traffic regions focussing on Southeast Asia, a region that has received much less ...

Selected topics on the interaction between cirrus clouds and embedded contrails [PDF]

open access: yesAtmospheric Chemistry and Physics, 2012
Persistent contrails and natural cirrus clouds often coexist in the upper troposphere and contrails can be embedded within cirrus clouds. The present paper deals with some questions regarding the interaction of cirrus clouds and embedded contrails.
