ahching Posted June 25, 2010 Posted June 25, 2010 Hi,I try to calculate a 1000m and 500m resolution map with the same region. Why the extreme wind results of 500m resolution are higher than 1000m resolution? Is there any possible explanation?
Duncan Posted June 25, 2010 Posted June 25, 2010 Are all of the values systematically higher? That would indicate a problem. If the maximum values are different between the maps, then it's not so surprising if the nodes of the grid map fall on different co-ordinates. To check this, you can put sites on the exact co-ordinates of the maximum value node in each map, and see what the predicted speed is for each.
Morten Posted July 2, 2010 Posted July 2, 2010 The WEng extreme-wind estimates depend on terrain-induces speed-up factors, which are calculated by the flow model. Using a too low resolution will typically result in too little terrain speed-up factors. Setting up a terrain model in WEng is a compromise between grid resolution and domain size with restrictions imposed by the available computer memory.

ahching Posted October 8, 2010 Posted October 8, 2010 The web page cannot be found???? Well, sometimes I could not open the project with a high resolution and big size map, but sometimes I could. So, Is that the problem with the computer memory?!
