A watershed simulation and forecasting system is widely used in Finland for simulation of hydrological cycle and for making real-time forecasts. The system is based on a watershed model. This was based originally on the HBV-model and simulates the hydrological cycle using standard meteorological data. The model simulates the whole land area of Finland, including cross-border watersheds. This is...

The heavy-fog statistics for 256 first-order weather stations were utilized to update analyses of the geographic distribution of f o g within the conterminous United States. The survey shows that heavy fog (visibility one-fourth mile or less) occurs more than 20 days a year at approximately 50 percent of the first-order weather stations (of which 229 are air terminals) and that the mean heavy-f...

A multi-site weather generator has been developed using the concept of spatial autocorrelation. The multi-site generation approach reproduces the spatial autocorrelations observed between a set of weather stations as well as the correlations between each pair of stations. Its performance has been assessed in two previous studies using both precipitation and temperature data. The main objective ...

Land evaluation is sensitive to the effects of annual variability in weather. A method to incorporate this variability into land evaluation systems is proposed, using the land capability system for Scotland as a case study. Land capability classes were found to be sensitive to the climate reference period from which data are taken. Individual stations rarely occupy their long-term land capabili...

The paper proposed a method of weather classification based on cloud model and hierarchical clustering. Firstly, according to the weather sampling data from FY-2C images, cluster the brightness values of five wave bands by hierarchical clustering approach based on cloud model, and generate the centres and the parameters of clusters of image features in different rainy weather types. Secondly, t...

Received Nov 1, 2017 Revised Jan 7, 2018 Accepted Jan 25, 2018 Weather forecasting is a significant function in meteorology and has been one of the most systematically challenging troubles around the world.This scheme deals with the structure of a weather display method using small cost components so that any electronics hobbyist can construct it. As a replacement for using sensors to collect t...

Common practice suggests that the assessment of wind and solar energy resources is based on data obtained from existing weather stations operated by the national meteorological services and other public services. Usually, these stations are placed at populated locations (for example airports, ports, urban, rural and protected areas) to support weather analysis, forecasts and warnings, local wea...
