Thats a lovely area you have there Abbe.
A wet thermometer bulb wouldn't work because the heat is not lost by convection as the wind does. It would be lost as conduction which although quicker is not the same effect because the volume of fluid is so small.
A wet bulb thermometer, in answer to Abbe, is a thermometer with a bit of wet cloth round the bulb. As the water evaporates, it cools the bulb, thus giving a lower reading than the dry bulb thermometer.
I had seen in meterological observations, "dry bulb" and "wet bulb" temperature readings, and thought that perhaps the wet bulb thermometer was there to give sime idea of wind chill...
I did a bit of googling since then, and found that it is more an indication of humidity.
In fact, the evaporation from the wet bulb thermometer depends on the humidity of the air. The less humidity there is, the faster the evaporation.
The difference in the readings, therefore, between the wet bulb thermometer and the dry bulb thermometer, give an indication of the humidity.
