My eighth grade classes study weather and we use a psychrometer to measure wet-bulb temperature as well as dry-bulb temperature. In the early fall when it is warm, our wet-bulb temperature usually matches fairly closely the dew point as reported at a local National Weather Service Automated Weather Reporting Site, but now - October in Minnesota - the reported dew point is usually significantly below the wet-bulb temperature no matter how long we whirl the psychrometer. For instance, this morning - Oct 5 - the dew point reported is 32 and our wet-bulb is 52. Is our technique faulty or should these be two different numbers?
Re: What is the difference between 'dew point' and 'wet-bulb temperature'?
