There is an increasing demand for large scale hydrological models not only in the field of modeling the impact of climate change on water resources but also for disaster risk assessments and flood or drought early warning systems. A high resolution global scale groundwater model. Since , tropical cyclones making landfall on the US Gulf of Mexico Coast have caused more than 9, deaths; nearly 2, deaths have occurred during the past half century. A new, high-resolution global mass coral bleaching database. We include a discussion of what processes can presently be parameterised in coupled models with coarse resolution non-eddying ocean models , and where parameterizations may fall short.

We present a fully three-dimensional, global electrical conductivity modrm of the Earth’s mantle as inferred from ground geomagnetic. A wide variety of processes are being studied to assess these integrations, in particular with regards to the role of resolution.
However, these areas are susceptible to some of the most destructive forces in nature, including tsunamis, floods, and severe storm-related hazards. We also investigate the optimal choice of input parameters for the finite-amplitude modelling methods. The model configuration needs to be “tuned and balanced” for the experiments.
In addition, model accuracy and the corresponding CIs varied depending on the soil variable of interest, soil depth and geographic csaper. By interpolation, we generated a DTM with a lateral spacing of HRR simulates hydrological processes using a Green-Ampt parameterization, and is calibrated against observed discharge data from several publicly-available datasets.

A recent development is the use of regional model dynamical downscaling for extended e. The resilience of Mycobacterium tuberculosis MTB is largely due to its ability to effectively counteract and even take advantage of the hostile environments of a host.
Atmospheric rivers in a hierarchy of high resolution global climate models: High-resolution models HRMs and low-resolution models LRMs are further investigated to demonstrate their different contributions to the uncertainties of the ensemble mean. We used the tie-points to carry out a photogrammetric block adjustment, which improves the image pointing and the accuracy of the ground point positions in three dimensions from about m to approximately 55 m.

These estimates of the variation of soil properties can be used to assess e. Water cycle changes over the Mediterranean: Therefore in this study we specifically address the consistency movem ” global ” and “regional” downscalings. Concern about how human-induced climate change will affect extreme events is increasing.
Furthermore, these results suggest that more detailed investigations into the impact of the GCM dynamical core on TC climatology are needed to fully understand these uncertainties.
Several efforts do exist that aim at the development of global gridded soil property databases. Stochastic parametrisations are used in weather and climate models as a physically motivated way to represent model error due to unresolved processes.
In this work, we present a pan European, high-resolution gridded dataset of meteorological observations EFAS-Meteo which was designed with the aim to drive a large scale hydrological model. In this talk, I will present the current and future developments of the cfa1 dynamical core” at the Data Assimilation Office.
We recently built an innovative Global Climate Model GCM for giant planets by coupling our complete seasonal radiative model [Guerlet Icarus ] with a new hydrodynamical solver using an original icosahedral mapping of the planetary sphere to ensure excellent conservation and scalability properties in massively parallel computing resources [Dubos GMD ].
In this paper, an attempt has been made to conduct a numerical experiment with the high-resolution global model GME to predict the tropical storms in the North Indian Ocean during the year The specifications of such data differ widely and therefore the harmonisation of data layers is a prerequisite to constructing detailed and contemporary spatial datasets which accurately describe population distributions.
Reliable power forecasts are however required for a grid integration of photovoltaic systems, which among other data requires high-resolution spatio-temporal global irradiance data. However, when models resolve finer scales, this may lead to the introduction of high-frequency variability which is not necessarily deterministic. Hydrodynamic friction and overland winds are adjusted to account for local land cover.
Biological uptake can have spatial variations related to complex, diverse vegetation, etc. cvs1
Overall, all models were considered robust; important indicators for this were 1 the small difference in model diagnostics between the calibration and cross-validation set, 2 the unbiased mean predictions, 3 the smaller spatial structure of the prediction residuals in comparison to the observations and 4 the similar performance compared to other developed Global SoilMap products. Addressing water resource problems in the Western U.
The maps shown depict flood depth and extent at different return periods. However, the creation of large scale datasets is challenging for it requires collection, harmonization, and quality checking of large amounts of observations. A high resolution global scale groundwater model. An efficient multi-scale double-difference DD algorithm is used to solve for relative event locations to the precision of a few km or less, while incorporating information on absolute hypocenter locations from catalogs such as EHB and GEM.
The relocations sharpen the view of seismicity in most active regions around the world, in particular along subduction zones where event density is high, but also along mid-ocean ridges where existing hypocenters are especially poorly located.
