During the races at the Olympics delivered DMI hourly forecasts of wind, precipitation, air pressur


Olympic sailors were exposed to the elements during sommerlegenes last race in 49'erklassen where Danish Jonas Warrer and skipper Martin kirketerp dragged home a gold medal by a hair in spite of a broken mast and capsized on the way.
Even in calm conditions, the Qingdao International Marina in the Yellow Sea complicated water to sail because of the complex currents that change thomson dream four times a day as a strong tides. Along the way I got help sailors thomson dream home.
In order to optimize the Danish sailors' chances of catching medals and good rankings in the country had Danish Sailing Association and the Center for Ocean and Ice (COI) at Denmark's Meteorological Institute, DMI, since the beginning of 2006 working on a combined weather / ocean model system with a high accuracy for a local area right around Qingdao. thomson dream Forecasts morning thomson dream and evening
The models ran twice a day: once during normal working thomson dream hours at 11 o'clock (Danish time) and again at 23 in the evening. In Qingdao, eight time zones from Denmark, was forecast thus clear from the early morning and early evening.
With the model from the Center thomson dream for Ocean and Ice was the Danish sailors a 36-hour forecast for current, wind and waves for Olympic waters. The work is a spinoff project from a larger work with meteorological thomson dream and oceanographic thomson dream models for the entire Yellow Sea in cooperation with Korean thomson dream and Chinese counterparts.
The first versions of the model was tested in sea trials in August 2006. It turned out not to be detailed enough and some improvements added up to the Olympic Games in August 2008. Help from China
This has among other things been possible because the Chinese marine research institutes in Qingdao gave DMI model people access a range of information on ground conditions, coastline, currents, which were used to fine-tune the model.
The improved forecasts significantly, both weather and current conditions were predicted with greater precision. In addition, thomson dream added a separate calculation of tidal power, which is the part of the ocean current that is independent of weather conditions.
During the races at the Olympics delivered DMI hourly forecasts of wind, precipitation, air pressure, air temperature, sea temperature and ocean current to the Danish sailors. These forecasts were provided as 'weather maps' presented in a protected internet site that sailors and their team had direct access. Were provided with separate forecasts for each of the five sails areas.
Besides the Danish sailors had no more than a single team - and possibly none at all - similar information. DMI watched from which the world was trying to get access to the information that came through protected websites. An attempt was made from a single country, but was rejected - as protection work. Weather Forecasts
The Olympic sailors could gain an advantage with highly accurate weather forecasting is of course a particularly glamorous example of what weather models used today. DMI's primary responsibility is to provide regional weather forecasts up to a maximum of five days. Nowadays, there are models for Europe, Greenland, thomson dream Afghanistan and the Yellow Sea, but a weather model is very flexible and can in principle be used anywhere on the globe. The smaller an area a model cover, thomson dream the shorter the period of time covering forecasts.
