Comparison between microphysical model simulation and observed cirrus clouds formation within a volcanic aerosol layer in the Tropical Tropopause Layer [PDF]
, 2012 In order to know the formation process of cirrus clouds in tropical tropopause layer, we used a microphysical numerical model to calculate nucleation and growing process of cirrus cloud particles, and compared the results of the model simulations with ...

Mission investigates tropical cirrus clouds [PDF]
Eos, Transactions American Geophysical Union, 2004 It has been 18 months since NASA conducted the highly successful Cirrus Regional Study of Tropical Anvils and Cirrus Layers‐Florida Area Cirrus Experiment Study (CRYSTAL‐FACE). The measurement campaign was designed to investigate the physical properties and formation processes of tropical cirrus clouds.

Impacts to the mountain‐valley circulation from the 2023 annular solar eclipse
Weather, EarlyView.In October 2023, as part of the Nationwide Eclipse Ballooning Project (NEBP), faculty and students from the University of North Dakota (UND) in coordination with Pueblo Community College Southwest collected weather observations during an annular solar eclipse colloquially known as a ‘ring of fire’ eclipse.

Journal of Management Studies, EarlyView.Abstract Integrating the attention‐based view with the strategic leadership interfaces perspective, we propose a theoretical model of situational urgency mechanisms influencing the allocation of CEOs' attention towards responsive actions. Specifically, we theorize upon the role of humility, which leads CEOs towards embracing interfaces and makes them ...

Influence of crystal shapes on radiative fluxes in visible wavelength: ice crystals randomly oriented in space [PDF]
Annales Geophysicae, 1996 Radiative properties of cirrus clouds are one of the major unsolved problems in climate studies and global radiation budget. These clouds are generally composed of various ice-crystal shapes, so we tried to evaluate effects of the ice-crystal shape on

First Observations of Cirrus Clouds Using the UZ Mie Lidar over uMhlathuze City, South Africa
Applied Sciences, 2022 Clouds cover more than two-thirds of the earth’s surface and play a dominant role in the energy and water cycle of our planet. Cirrus clouds are high-level clouds composed mostly of ice crystals and affect the earth’s radiation allocation mainly by ...

Halo ratio from ground based all-sky imaging [PDF]
, 2018 © Author(s) 2019.The halo ratio (HR) is a quantitative measure characterizing the occurrence of the 22 halo peak associated with cirrus. We propose to obtain it from an approximation to the scattering phase function (SPF) derived from allsky imaging ...

Measurement and modeling of diffuse ultraviolet radiation: A review
Photochemistry and Photobiology, EarlyView.Solar UV radiation consists of direct and diffuse UV components. The diffuse component contributes to the exposure received by humans and to the risk of skin cancer and sun‐related eye disorders. This review aims to determine future research directions for the measurement and modeling of diffuse solar UV radiation.
