what do you use to measure wind?

The wind does not affect a thermometer's temperature reading.  It affects you because you evaporate sweat more quickly, which is cooling, and because it blows away all the warm places you store in clothes and body parts.\n\nThe Stevenson's shield that meteorologists use to keep temperature, shields the thermometer from the sun (so as to get a shade reading, which is the only reliable reading), but has vent opening to the air.

I don't know what country you are from so I will answer for the UK ... Maplin Electronics have cheap (no soldering) wind power kits.\n\nIf you are from another country find a hobby electronics store and ask them about kits like this - they are very common items.\n\nGood luck

You'll actually make the measurement worse. Think about the math without going in to numbers too much. Let's say we have 30 arms (yeah, I know, too many). Only one of them at a time is nearly perpendicular to the wind force. It's plus/minus 6 degrees. By the time that one move past that 6 degrees the next is coming in. Think about the sines and cosines - the force parallel and perpendicular - nearly 100% is going in the direction of the wind. It moves that blade just about right.\n\nNow go from 30 to 3 blades.Each blade now covers 120 degrees. That makes them the most perpendicular plus/minus 60 degrees. Now look at the sines and cosines of the forces. You actually get quite a bit of force slowing down your reading. If you hooked up your anemometer to an o'scope, you would see a pretty drastic fluctuation in speed variance. The more arms, the flatter that variance becomes.

Well an easy one is the thermometer of corse for the temperature \n\nAnother will be your barometer this instament measures pressure of the atmosphere (lower pressure a good signal for bad weather) \n\nThe anamometer we use to measure wind speed and direction \n\nNow one of the ccolest instaments we have is a laser cieliometer...aka(LBC) this device measures cloud heights by firing an invisible laser into the air, however it is only good up to 12,000ft AGL (above ground level)\n\nTransmisometer-runway visual range\nWSR-88D(Radar)- storm location, movement, intesity, direction...ect\n\nThere are several instaments we use....one of the best resources other than this might be to go to the local news station.

Have a look at my project.  Several links for pictures, wiring, charge controller, and so on.\nhttp://members.rennlist.org/warren/wind.html

Not sure about forecast, but Kestrel makes some amazing anemometers (wind meters), some with barometers and altimeters built in.

Take a compass and a bar magnet and let them trace the field lines. Or better yet, take a piece of paper with metal shaving on it, then place a magnet underneath. The shaving will align with the field lines. Pretty cool.

If you want a cheap and complete station buy a lacrosse weather station at Sam's Club for about $100.  A Davis weather station is also very good but more expensive.

A radiometer does what you describe. \n\nhttp://store.sundancesolar.com/solrad.html\n\n\nDirections to build a simple radiometer:\n\nMake a radiometer to measure solar energy. Colour the paper side of a gum wrapper black and cut in four pieces. Stick the pieces to each side of a match stick with the shiny sides all facing the same way. Wrap a thread around a pencil and attach to the match stick. Suspend in the jar and place in a sunny location. The radiometer will turn as it absorbs energy.
