Weather and Cloud Symbols: The Heritage of Hand-Plotted Weather Maps

Finding Structures in Weather Maps

We describe an eeective computational method for extracting structural information from spatial data sets. For instance, the structural information such as the location, shape, size, and movement about pressure cells and troughs are important for weather prediction. We are interested in extracting these structures and representing them at aggregate levels where salient geometric features are hi...

Research Environment and Information Service of the Space Weather Cloud

For researches and information services of space weather, it is important to establish a comprehensive system which enables us to analyze observation and simulation data in an integrated manner. For this, we constructed recently a new computing environment called the “Space Weather Cloud Computing System” of the National Institute of Information and Communications Technology (NICT). Now, the Sp...

The Polygon-Ellipse Method of Data Compression of Weather Maps

Weather Conditions, Weather Information and Car Crashes

Road traffic safety is the result of a complex interaction of factors, and causes behind road vehicle crashes require different measures to reduce their impacts. This study assesses how strongly the variation in daily winter crash rates associates with weather conditions in Finland. This is done by illustrating trends and spatiotemporal variation in the crash rates, by showing how a GIS applica...

sources of dust storms in south west iran using satellite images and weather maps

introduction the dust storms are one of the climatic hazards in the dry climates of the world. they cause many damages to the environment and humans. one of the aspects of a study to understand the origin of this phenomenon is the formation of foci in the recent years in the areas of research. it has been done in the central regions. the dust storms have gained global scale. this has demonstrat...
