Interactions Between Clouds, Atmospheric Boundary-Layer, and Snow-Covered Sea Ice during the SHEBA WinterIn addition, these same processes and process relationships are be examined in simulations with the Weather Research and Forecasting Model (WRF) and in reanalysis data, which are primarily dependent...
During the West African summer monsoon season, extended nocturnal stratiform low-level clouds (LLCs) frequently form in the atmospheric boundary layer over southern West Africa and persist long into the following day affecting the regional climate. A unique data set was gathered within the framework...
Cumulus clouds in the atmospheric boundary layer play a key role in the hydrologic cycle, in the onset of severe weather by thunderstorms, and in modulating the Earth's reflectivity and climate. How these clouds respond to climate change, in particular over land, and how they interact with the...
This study investigates the dynamics of atmospheric clouds and boundary layer due to a sudden dust storm over Ahmedabad (23.02掳 N, 72.57掳 E), a Western-Indian region, during the pre-monsoon season on May 13, 2024. The storm was triggered by the outflow from convective systems originating ...
What are noctilucent clouds made from? NLCs are made from ice crystals, which makes them similar to the wispy cirrus clouds seen in the lower atmosphere. However, as a result of the very low density of the air in which they form, NLCs are much less substantial than cirrus clouds. This ...
Magnetic field strengths in dense clouds are measured by Zeeman splitting of molecular lines, and are found to be large enough (∼10–1,000 μG) to be capable of supporting clouds, when both static magnetic fields and MHD waves are present (Crutcher, 1999). Field strengths are found to...
The CALIOP observations indicate that a cloud layer is often present below TMLCs with an annual occurrence of 38%. Clouds below TMLCs are predominantly shallow cumulus formed on top of the active mixing layer (that is, with a top altitude of about 2–3 km)5. By considering a cloud layer...
find good agreement with theory. Ion-induced condensation should be of importance not just in Earth’s present day atmosphere for the growth of aerosols into cloud condensation nuclei under pristine marine conditions, but also under elevated atmospheric ionization caused by increase...
In the following sections, we utilize the different scattering models to perform the gas and hydrometeors attenuation corrections for the triple-frequency radar. The ECMWF reanalysis data are used in this study for the atmospheric vertical profile information. For calculating the attenuation, we assume...
In this work, collocated lidar–radar observations are used to retrieve the vertical profiles of cloud properties above the Eastern Mediterranean. Measurements were performed in the framework of the PRE-TECT experiment during April 2017 at the Greek atmospheric observatory of Finokalia, Crete. Cloud ...
