Numerical models are starting to be used for determining the future behaviour of seismic faults and fault networks. Their final goal would be to forecast future large earthquakes. In order to use them for this task, it is necessary to synchronize each model with the current status of the actual fault or fault network it simulates (just as, for example, meteorologists synchronize their models wi...

Meteorologists use shapes and movements of clouds in satellite images as indicators of several major types of severe storms. Satellite imaginary data are in increasingly higher resolution, both spatially and temporally, making it impossible for humans to fully leverage the data in their forecast. Automatic satellite imagery analysis methods that can find storm-related cloud patterns as soon as ...

Improved understanding of characteristics related to weather forecast accuracy in the United States may help meteorologists develop more accurate predictions and Americans better interpret their daily forecasts. This article examines how spatio-temporal across relate accuracy. We cluster into six regions based on geographic analyze patterns within each region. then explore relationship between ...

Large archives of historical meteorological data offer novel opportunities for weather forecasting and meteorological research. However, effective exploitation of such an archive is impeded by the logistics of managing large volumes of data and the difficulty of identifying relevant data. MetVUW Workbench is a case retriever that allows meteorologists to identify relevant past weather situation...

Automatic detection of severe weather events is of great interest to meteorologists. In this paper, we describe and evaluate a method to identify hook echoes automatically in radar reflectivity data. The method is based on the skeletonization of 2D shapes which are used to describe the shape of storms. We use 4 skeleton shape features: curvature, curve orientation, thickness variation and bound...

An agent oriented approach is well suited for complex application domains, and often when such applications are used by domain experts they identify modifications to be made to these applications. However, domain experts are usually limited in agent programming knowledge, and are not able to make these changes themselves. The aim of this work is to provide support so that domain experts are abl...

We herein describe the recovery of a series of data on temperature, humidity, precipitation, evaporation, wind, and local weather conditions from documentary sources obtained from the Jesuit observatory of A Guarda (Galicia, Spain) for the period 1881-1896. The data were digitized and made available in accessible electronic formats. Comparisons were made with present-day meteorological data obt...
