This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because atmospheric deep convection plays an important role in influencing Earth's global energy budget, it is increasingly important to consider how deep convective cloud and energetic properties might change due to a changing climate. Deep convective vertical intensity may increase in regions that are becoming increasingly moist in response to warming sea surface temperatures, which could alter precipitation, anvil cloud development, and their radiative response. The focus of this work, therefore, is to document the relationships between these properties applied to our present-day understanding of how convection fundamentally contributes to the Earth's energy budget: by 1) vertically transporting energy and mass to the upper troposphere, 2) balancing clear-sky radiative cooling through latent heating, and 3) modulating the top-of-atmospheric radiative energy budget. The processes influencing how convective updraft strength relates to cloud and precipitation development occur on the convective cloud scale and smaller, so it is necessary to document such characteristics on these scales. We begin by providing a near-global perspective of convection using a database of "convective objects" generated from ten years of A-Train measurements. By leveraging CloudSat's ability to distinguish convective cores, we define a proxy for a convective core vertical intensity based on the height of the attenuating radar signal. Over the tropics, these observations support previous insights from a precipitation perspective on where storms are the most intense. Motivated by wanting to understand deep convective contributions to lateral energy transport, we next document how the intensity and frequency of deep convective cores that reach the tropopause (hot towers) relate to anvil cloud and precipitation productivity within the tropics. It is found that the largest amount of mass within the upper troposphere supplied by hot towers is not geographically where the most precipitation and largest anvil extents occur. Motivated by convection's influence on the top-of-atmospheric radiative energy budget, we analyze how convective core depth and anvil structure influence their cloud radiative effects. We find that the most vertically intense systems more often contribute a warming at the top of the atmosphere compared to weaker systems, which holds across different regions in the tropics. Finally, we explore how these relationships are sensitive to large-scale environmental conditions to provide benchmark relationships for modeling studies assessing high cloud feedbacks in a changing climate.

This book was released on 2022-10-26 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: Clouds, convection and precipitation processes are central components of Earth's weather and climate. They are produced by atmospheric motions across a very wide range of space-time scales from local weather to long-term global climate variation. They feedback on these motions by perturbing the heating/cooling that drive the atmospheric circulation. These processes also perturb the oceanic circulation and land surface properties that affect the atmospheric circulation.Because of the coupling of the atmosphere-ocean-land system across all scales by cloud, convection and precipitation processes, studying their behaviors requires measurements in space-time variations across all these scales simultaneously. Satellite constellations with global coverage and high time resolution offer the ideal platforms for such observations. This book summarizes some of the latest research using combinations of various satellite observations to study these processes and to evaluate their representations in global weather and climate models.Included with this publication are downloadable electronic slides and accompanying notes of each lecture for students, teachers, and public speakers around the world to be better able to understand cloud, convection and precipitation processes.

Download or read book An Observational Study of Entrainment Rate in Deep Convection written by and published by . This book was released on 2015 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study estimates entrainment rate and investigates its relationships with cloud properties in 156 deep convective clouds based on in-situ aircraft observations during the TOGA-COARE (Tropical Ocean Global Atmosphere Coupled Ocean Atmosphere Response Experiment) field campaign over the western Pacific. To the authors' knowledge, this is the first study on the probability density function of entrainment rate, the relationships between entrainment rate and cloud microphysics, and the effects of dry air sources on the calculated entrainment rate in deep convection from an observational perspective. Results show that the probability density function of entrainment rate can be well fitted by lognormal, gamma or Weibull distribution, with coefficients of determination being 0.82, 0.85 and 0.80, respectively. Entrainment tends to reduce temperature, water vapor content and moist static energy in cloud due to evaporative cooling and dilution. Inspection of the relationships between entrainment rate and microphysical properties reveals a negative correlation between volume-mean radius and entrainment rate, suggesting the potential dominance of homogeneous mechanism in the clouds examined. The entrainment rate and environmental water vapor content show similar tendencies of variation with the distance of the assumed environmental air to the cloud edges. Their variation tendencies are non-monotonic due to the relatively short distance between adjacent clouds.
