Reconstructing Earth's Temporal Evolution
ISBN: 9783838380803 / Angielski / Miękka / 184 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. How the planet Earth evolves to its present form and how the interior of Earth affects its surface are still open questions. The main difficulty in probing the answer is the incomplete knowledge of Earths internal structures, especially at the ancient geological past. This book introduces a novel approach to reproduce the evolving interior of Earth, using a technique widely adopted in weather prediction. An inverse model based on this technique can crank the time machine backward, and reveal the Earths structure in the past. An example is the reconstruction of the so called Farallon...

Scaling Up Landcare in the Philippines
ISBN: 9783838314150 / Angielski / Miękka / 360 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The developing world is not lacking in successful grassroots initiatives for Natural Resource Management but few of these have spread beyond their initial limited domain. The issue of scaling up has recently gained attention based on the argument that these successful local NRM initiatives should be scaled up to a level that generates larger economic and environmental benefits more rapidly. Scaling is viewed as a process of planned intervention. The notion of scaling up thus involves finding a balance between a universalist perspective, where broad principles and practices are believed to be...

On Mixed Wind-Sea/Swell Conditions in the Open Ocean
ISBN: 9783838371207 / Angielski / Miękka / 112 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. A number of studies have aimed to find those factors affecting the drag coefficient at the ocean surface. The direction of swell relative to the local wind has been proposed as a contributing factor. Different approaches have been used, but the results have been inconclusive. Here observed and modelled 2D wave spectra are compared. The data is obtained by the microwave MIROS-radar and the WAM-model (cycle-4) at different locations in the North Sea and Norwegian Sea. Based on the fact that the WAM source functions are not accounting for swell effects, a difference between the observed and...

Empirical Methods in Climate Modeling
ISBN: 9783838340883 / Angielski / Miękka / 200 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Numerous works have been completed in the atmospheric science modeling community based on changing or replacing of parameterization schemes with other schemes. However, few studies have considered how to make these models less time- consuming. Most of the changes that are made to models involve increasing their degree of complexity (and time burden) as opposed to their simplicity. However, a recent study showed that the processing time of the CAM2 climate model was sped up 50-80 times by replacing its longwave parameterization scheme with a neural network. In this book, we show...

The convective cloud field model
ISBN: 9783838345123 / Angielski / Miękka / 256 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The parameterisation of clouds in global climate models has been recognised for decades as a source of substantial uncertainty concerning the estimates of climate variability and sensitivity. The IPCC AR4 lists convective clouds as one of the major problems in global climate modeling. Precipitation remains one of the least reliable variables in climate models and extreme precipitation is especially problematic, being highly sensitive to the parameterisation of convection. A realistic treatment of the physical processes associated with convective clouds is of great importance for many physical...
