Water Vapor Distribution in the Sub-cloud Trade Wind Air


Book Description

OBSERVATIONS OF THE MIXING RATIO WERE MADE SIMULTANEOUSLY AT THREE LEVELS IN THE SUB-CLOUD LAYER OF THE TRADE WIND EAST OF THE Bahama island of Eleuthera. Three airplanes were equipped with psychrographs capable of yielding significant 3-second averages of the mixing ratio. On 8 days, August 8 to 16, 1960, 41 formation flights were made on east-west or north-south courses, giving 123 series of mixing ratios for analysis. Runs extended over 10 or 20 minutes and the evels were usually 400, 800, and 1200 feet.




Physics of the Marine Atmosphere


Book Description

International Geophysics Series, Volume 7: Physics of the Marine Atmosphere discusses the influence exerted by the sea surface on the properties of the atmosphere as well as on atmospheric processes of small and medium scale. This book is composed of six chapters that specifically consider the exchange occurring in the boundary layer between ocean and atmosphere. The opening chapters deal with the particular difficulties inherent in meteorological measurements at sea. The remaining chapters describe the flow characteristics, thermodynamics, chemistry, electricity, and radioactivity of the marine atmosphere. Emphasis is placed on the physical approach rather than on geographical aspects and those of application. A discussion of the empirical facts is followed by theoretical interpretation. Geophysicists, theoreticians, and scientists of the allied fields will find this book invaluable.




Shallow Clouds, Water Vapor, Circulation, and Climate Sensitivity


Book Description

This volume presents a series of overview articles arising from a workshop exploring the links among shallow clouds, water vapor, circulation, and climate sensitivity. It provides a state-of-the art synthesis of understanding about the coupling of clouds and water vapor to the large-scale circulation. The emphasis is on two phenomena, namely the self-aggregation of deep convection and interactions between low clouds and the large-scale environment, with direct links to the sensitivity of climate to radiative perturbations. Each subject is approached using simulations, observations, and synthesizing theory; particular attention is paid to opportunities offered by new remote-sensing technologies, some still prospective. The collection provides a thorough grounding in topics representing one of the World Climate Research Program’s Grand Challenges. Previously published in Surveys in Geophysics, Volume 38, Issue 6, 2017 The aritcles “Observing Convective Aggregation”, “An Observational View of Relationships Between Moisture Aggregation, Cloud, and Radiative Heating Profiles”, “Implications of Warm Rain in Shallow Cumulus and Congestus Clouds for Large-Scale Circulations”, “A Survey of Precipitation-Induced Atmospheric Cold Pools over Oceans and Their Interactions with the Larger-Scale Environment”, “Low-Cloud Feedbacks from Cloud-Controlling Factors: A Review”, “Mechanisms and Model Diversity of Trade-Wind Shallow Cumulus Cloud Feedbacks: A Review”, “Structure and Dynamical Influence of Water Vapor in the Lower Tropical Troposphere”, “Emerging Technologies and Synergies for Airborne and Space-Based Measurements of Water Vapor Profiles”, “Observational Constraints on Cloud Feedbacks: The Role of Active Satellite Sensors”, and “EUREC4A: A Field Campaign to Elucidate the Couplings Between Clouds, Convection and Circulation” are available as open access articles under a CC BY 4.0 license at link.springer.com.

On the Structure of Trade-wind Air Below Cloud


Book Description

The moisture and temperature structure of the trade-wind mixed layer are compared under conditions of strong versus weak trade. The data used are two series of aircraft psychrograph soundings made over the ocean near Puerto Rico in early spring. The first in conditions of strong undisturbed trade and high zonal index (April 10 - 28, 1946) and the second under conditions of weak rather disturbed trade and low zonal index (March 18 - April 7, 1953). The weak trade soundings show a less homogeneous moisture distribution and a less stable temperature lapse rate. Considerable variation in structure of the lowest air accompanies changes in the trade regime which may give rise to significant fluctuations in energy input at the source region for atmospheric circulations. The importance of wind stirring in the upward transfer of moisture is indicated, which may affect the formation of trade cumulus clouds. Further studies investigating the relation between air and ocean structure at their boundary are suggested by the evidence herein, which may relate to the formation of tropical storms.
