Download or read book An Analytical Soil Thermodynamic Model for the Diurnal Variation of Ground Surface Temperature written by Samuel Y. K. Yee and published by . This book was released on 1987 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analytical expression is given for time variations of temperature within a model soil slab that is subjected to idealized heating at the supper surface and maintained at constant temperature at the lower surface. Applied at the upper surface, the model temperature may be considered to be the ground surface temperature of the earth. An important feature of this model is that phase-shifted on-linear responses to the forcing are allowed at the upper boundary. The analytical nature of the solution enables us to easily study the relative importance of various physical processes in the model surface energy budget equation. For example, evaporational cooling is found to be an important feedback process under model summer conditions, accounting for a change of about 6K in the daily mean surface temperature; under winter conditions, the change attributable to evaporation is only about 1K. The perturbation method used in our approach to linearize the model upper boundary condition is shown to be applicable to more complicated and more realistic upper boundary conditions.

Download or read book Data Models and Analysis written by Guoqi Han and published by Routledge. This book was released on 2019-07-09 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the ten most cited articles that have appeared in the journal Atmosphere-Ocean since 1995. These articles cover a wide range of topics in meteorology, climatology and oceanography. Modelling work is represented in five papers, covering global climate model development; a cumulus parameterization scheme for global climate models; development of a regional forecast modelling system and parameterization of peatland hydraulic processes for climate models. Data rehabilitation and compilation in order to support trend analysis work on comprehensive precipitation and temperature data sets is presented in four papers. Field studies are represented by a paper on the circumpolar lead system. While the modelling studies are global in their application and applicability, the data analysis and field study papers cover environments that are specifically, but not uniquely, Canadian. This book will be of interest to researchers, students and professionals in the various sub-fields of meteorology, oceanography and climate science.

Download or read book GOALS Global Ocean Atmosphere Land System for Predicting Seasonal to Interannual Climate written by National Research Council and published by National Academies Press. This book was released on 1994-02-01 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book lays out a science plan for a major, international, 15-year research program. The past 10 years have seen significant progress in studies of short-term climate variations, in particular for the region of the tropical Pacific Ocean and the El Nino/Southern Oscillation phenomenon. Some forecast skill with lead times as long as a year in advance has already been developed and put to use. The GOALS program plans to capitalize on this progress by expanding efforts on observations and seasonal-to-interannual predictions to the remainder of the tropics and to higher latitudes.

Download or read book Coupled Dynamics in Soil written by Yijian Zeng and published by Springer Science & Business Media. This book was released on 2012-12-14 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: In arid and semi-arid areas, the main contributions to land surface processes are precipitation, surface evaporation and surface energy balancing. In the close-to-surface layer and root-zone layer, vapor flux is the dominant flux controlling these processes - process which, in turn, influence the local climate pattern and the local ecosystem. The work reported in this thesis attempts to understand how the soil airflow affects the vapor transport during evaporation processes, by using a two-phase heat and mass transfer model. The necessity of including the airflow mechanism in land surface process studies is discussed and highlighted.
