Measurement of Water in the Air
The amount of water in the air can be measured in different ways. The specific humidity of air is a measure of how much water is in the air. Warmer air can hold more water than colder air. When the air reaches its capacity, it is saturated. This capacity doubles for about every 11°C rise in temperature. The term more often used is relative humidity. This is the measure of how much water is in the air divided by how much it can hold. The relative humidity reading is given as a percent. The relative humidity for saturated air is 100 percent.
Finding Relative Humidity
The relative humidity can be found by two different methods. One involves the use of a hygrometer. This is a pointer attached to a piece of hair. As the humidity increases, the hair stretches out. This is your typical “bad‐hair day.” When the humidity drops, the hair shrinks, causing the needle to point in a different direction. The other method requires the use of two thermometers and a chart. The thermometers and chart all use the Celsius scale. If you are getting the readings from a station model and need to find the relative humidity, you need to convert the temperature readings from Fahrenheit to Celsius. Station models show the surface observations and weather data for a specific city. One of the thermometers measures the air temperature. This is the dry‐bulb reading. The other thermometer has a wet wick on the bottom of the bulb. Water evaporating from the wick into the air takes energy with it, cooling off the thermometer. As the relative humidity increases, less water can evaporate into the air. This makes the temperature readings between the two thermometers closer. If the air is much drier, the thermometers have readings that are much farther apart. The difference between the wet and dry‐bulb temperatures is called the wet‐bulb depression. The wet‐bulb temperature is always lower or the same as the dry‐bulb temperature. If the temperatures are the same, the relative humidity is 100 percent. The wet‐bulb depression is used with the dry‐bulb temperature and a chart to determine the relative humidity. Table shows this chart.
