The Oscillating Boundary Phenomenon in the Homogenization of a Climatization Problem [PDF]

open access: possibleDifferential Equations, 2001
Let \(\Omega\subset\mathbb{R}^2\) be a bounded domain, \(\varepsilon>0\) a small parameter and \(\Omega_\varepsilon\) the domain obtained by \(\varepsilon\)-periodic perturbation \(\partial\Omega_\varepsilon\) (with the amplitude \(\varepsilon)\) of the boundary \(\partial\Omega\). The author considers a homogenization of the stationary heat conduction

Homogenization results for climatization problems

ANNALI DELL'UNIVERSITA' DI FERRARA, 2007
This paper deals with the homogenization of a nonlinear model for heat conduction through the exterior of a domain containing periodically distributed conductive grains. We assume that on the walls of the grains we have climatizators governing the heat flux through the boundary.

Intensification and spatial homogenization of coastal upwelling under climate change

Nature, 2015
The timing and strength of wind-driven coastal upwelling along the eastern margins of major ocean basins regulate the productivity of critical fisheries and marine ecosystems by bringing deep and nutrient-rich waters to the sunlit surface, where photosynthesis can occur.

Homogeneous Climate Regions Using Learning Algorithms

2018
Climate analysis is extremely useful to understand better the differences of electricity consumption within the French territory and to help electricity consumption forecasts. Using a large historical data base of 14 years of meteorological observations, this work aims to study a segmentation of the French territory based on functional time series of ...

Climate Change: Use of Non-Homogeneous Poisson Processes for Climate Data in Presence of a Change-Point

Environmental Modeling & Assessment, 2021
In this study, non-homogeneous Poisson processes (NHPP) are used to analyze climate data. The data were collected over a certain period time and consist of the yearly average precipitation, yearly average temperature and yearly average maximum temperature for some regions of the world.

Climate and regional resource analysis: The effect of scale on resource homogeneity

Climatic Change, 1988
General Circulation Models (GCMs) are currently used to project future climate. The output of the models is then used to evaluate the effect of a climatic change on resources such as agriculture, forestry, and water resources. The GCMs used in long-term climate studies vary widely in the geographic resolution of their predictions.

The uncertainty of break positions detected by homogenization algorithms in climate records

International Journal of Climatology, 2015
ABSTRACTLong instrumental climate records suffer from inhomogeneities due to, e.g. relocations of the stations or changes in instrumentation, which may introduce sudden jumps into the time series. These inhomogeneities may mask or strengthen true trends.

BUILDING HOMOGENEITY WITH CLIMATIC FACTORS TO ACHIEVE SUSTAINABLE DESIGN

Urbanizm, 2019
With the advent of modern architecture and the ever-increasing use of mechanical facilities, the importance of climate in architectural design was underestimated. However, due to reduction of the oil reservoirs and pollutions in cities and the irreparable damage of fossil fuels to the environment, attention to the climate and climate design was ...

Homogenization of Climate Data: Review and New Perspectives Using Geostatistics

Mathematical Geosciences, 2008
The homogenization of climate data is of major importance because non-climatic factors make data unrepresentative of the actual climate variation, and thus the conclusions of climatic and hydrological studies are potentially biased. A great deal of effort has been made in the last two decades to develop procedures to identify and remove non-climatic ...

A Bayesian normal homogeneity test for the detection of artificial discontinuities in climatic series

International Journal of Climatology, 2010
AbstractA Bayesian Normal Homogeneity Test (BNHT) for the detection of artificial discontinuities in climatic series is presented. The test is simple to use and allows the integration of prior knowledge on the date of change from various sources of information (e.g. metadata or expert belief) in the analysis.
