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

Atmospheric 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.

Subvisible cirrus clouds – a dynamical system approach [PDF]

Nonlinear Processes in Geophysics, 2017
Ice clouds, so-called cirrus clouds, occur very frequently in the tropopause region. A special class are subvisible cirrus clouds with an optical depth lower than 0.03, associated with very low ice crystal number concentrations. The dominant pathway

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

Tellus: 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]

Atmospheric 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

Geophysical 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 ...

Modelling of cirrus clouds – Part 1b: Structuring cirrus clouds by dynamics [PDF]

Atmospheric Chemistry and Physics, 2009
Abstract. A recently developed and validated bulk microphysics scheme for modelling cirrus clouds (Spichtinger and Gierens, 2009), implemented into the anelastic non-hydrostatic model EULAG is used for investigation of the impact of dynamics on the evolution of an arctic cirrostratus.

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

Atmospheric 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 ...
