Vertical Structures of Anvil Clouds of Tropical Mesoscale Convective Systems Observed by CloudSat
A global study of the vertical structures of the clouds of tropical mesoscale convective systems (MCSs) has been carried out with data from the CloudSat Cloud Profiling Radar. Tropical MCSs are found to be dominated by cloud-top heights greater than 10 km. Secondary cloud layers sometimes occur in MCSs, but outside their primary raining cores. The secondary layers have tops at 6–8 and 1–3 km. H...
متن کاملDiscriminating raining from non-raining clouds at mid-latitudes using multispectral satellite data
We propose a new method for the delineation of precipitation using cloud properties derived from optical satellite data. This approach is not only sufficient for the detection of mainly convective precipitation by means of the commonly used connection between infrared cloud top temperature and rainfall probability but enables the detection of stratiform precipitation (e.g., in connection with m...
متن کاملDiscriminating raining from non-raining clouds at mid-latitudes using Meteosat Second Generation daytime data
A new method for the delineation of precipitation during daytime using multispectral satellite data is proposed. The approach is not only applicable to the detection of mainly convective precipitation by means of the commonly used relation between infrared cloud top temperature and rainfall probability but enables also the detection of stratiform precipitation (e.g. in connection with mid-latit...
متن کاملGlobal Variability of Mesoscale Convective System Anvil Structure from A-Train Satellite Data
Mesoscale convective systems (MCSs) in the tropics produce extensive anvil clouds, which significantly affect the transfer of radiation. This study develops an objective method to identify MCSs and their anvils by combining data from three A-train satellite instruments: Moderate Resolution Imaging Spectroradiometer (MODIS) for cloud-top size and coldness, Advanced Microwave Scanning Radiometer ...
متن کاملEmbedding Epistemic Modals
Seth Yalcin has pointed out some puzzling facts about the behaviour of epistemic modals in certain embedded contexts. For example, conditionals that begin 'If it is raining and it might not be raining, …' sound unacceptable, unlike conditionals that begin 'If it is raining and I don't know it, …'. These facts pose a prima facie problem for an orthodox treatment of epistemic modals, according to...
