Biological echoes are treated as contamination like ground or sea clutters by radar meteorologists as they estimate rainfall intensities or assimilate radar reflectivity into numerical forecast model. Doppler velocity measured by radar in the presence of small insects well represents air motion because small insects are considered as passive tracers. But in the presence of birds especially migr...

Chaos is a fundamental property that possesses nonlinearity and a sensitive dependence on initial conditions. Because of the nonlinearity in a chaotic system it becomes very difficult to make accurate predictions about the system over a given time interval. Weather forecasting is an example of how chaos theory effects the accuracy of predictions over a given time interval. Through analyzing a w...

The WWW is increasingly being used as a platform for the presentation of distance education courses. Such a medium has a number of important advantages, among them easy world-wide access to the courses, and ease and flexibility in updating course materials. The Australian Bureau of Meteorology’s Training Centre is participating in a European-based project known as EuroMET (the European Meteorol...

The Meteorological Service of Cyprus operates a Doppler radar at the mountainous region of the island. Data-streams recorded by the radar are used for weather forecasting and, especially, for identifying oncoming precipitation incidents and issuing (potential) warnings. However, the continuous processing and evaluation of radar data requires significant efforts by the meteorologists, both for d...

Scientific evidence accumulated over the last decade indicates that weather radar polarimetry has passed two important tests. First, as suggested by theory, polarimetric signals contain significant information about hydrometeor habits; and second, the information can be retrieved with sufficient accuracy to be useful. If it passes the cost effectiveness test, the technique should be adopted for...

In a research project funded by the German Research Foundation, meteorologists, data publication experts, and computer scientists optimised the publication process of meteorological data and developed software that supports metadata review. The project group placed particular emphasis on scientific and technical quality assurance of primary data and metadata. At the end, the software automatica...

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...
