isobars
There is no key, but there are three windmills you have to blow in to. There will be a map. When the wind is blowing click on the map and it show an x. Go there and it will show you the three wind mills you're supposed to blow into. Blow into the three wind mills and the door will open
Closely spaced isobars indicate large pressure changes over a small area and suggest strengthening winds.Widely spaced isobars portray a "flat" or weak pressure gradient typical of light-wind situations.
It shows direction and wind speed in knots.
it is in the map that shows the earth wind system
Isobars, lines on a weather map connecting points of equal atmospheric pressure, can tell you about wind speed by showing areas where pressure gradients are strongest. The closer isobars are together, the stronger the pressure gradient and the faster the wind speed. Wind will flow from high pressure to low pressure areas along isobars.
One look at the wind map of Europe, one can see the average wind speed for the last 180 minutes. Altitude of 10 meters above ground is shown.
Few modern maps use the compass rose. The pictures of dragons and clouds with faces blowing the wind and the elaborate compass rose with the four cardinal points and the intermediate points forming a rose-like blossom went out in the 1800s. Today, the map will probably have only an austere north arrow to help you orient the map to your course.
If a weather map shows a wind symbol at 270 degrees, it means the wind is coming from the west. Wind direction is typically reported in terms of where it is coming from, not where it is going to.
