You must have seen the weather forecasting or basic weather details on the mobile phones etc which generally shows these two things i.e the temperature of the place and the humidity. These two are also related to each other and show great impact as well. They both lead to having impacts on the flora, fauna as well as environment as well. In this article, we will be only discussing the relation between temperature and humidity and other related concepts where we learn about the meaning of temperature, humidity, types of humidity, the relation between humidity and temperature formula, dew point or moisture, etc.Â

## Temperature Humidity Relationship

Temperature is something that tells us about the coldness or warmness of any object which is generally measured in celsius and Fahrenheit. It determines the intensity of the heat whereas if we talk about humidity, it talks about the water content that presents in the air, or simply we can say it determines the moisture of the air. These two concepts are different but show a great impact on each other. We will see the relation between temperature and humidity further below. Before that, let's understand more about the humidity and its types.

### Absolute Humidity & Relative Humidity

There are generally two types of humidity ie. absolute and relative. The former tells the humidity present in a parcel of air without taking temperature into consideration whereas the latter tells the humidity present in the air with respect to the temperature of the air. The former defines the amount of water content by dividing the weight of the parcel by its volume whereas the latter is calculated by dividing the amount of water content present divided by the total capacity of the parcel of the air to hold multiplied by 100. The former decreases with height whereas the latter when reaching 100%, the air gets saturated.

### Relation Between Relative Humidity and Temperature

We have already learned what is temperature and what is humidity and we have also learned two types of humidity. As we know, both these two concepts ie. Temperature and Humidity are different but they are related to each other. The relation between humidity and temperature formula simply says they are inversely proportional. If temperature increases it will lead to a decrease in relative humidity, thus the air will become drier whereas when temperature decreases, the air will become wet means the relative humidity will increase.

Here, in this graph we can see that on the x-axis we have temperature whereas on the y - axis we have relative humidity and the three different ranges in the graph shows which is an acceptable range and which is not. For example, a region with a temperature of 18Â° and relative humidity of 40% is considered as too dry whereas the region with 23Â° temperature and 70% relative humidity comes in the range of too moist regions. The regions between these two extremes are acceptable such as regions with 24Â° temperature and 50% humidity. In this way, their relationship affects the region.

### Relationship Between Humidity and Dew Point

Air usually contains moisture at a particular level and when the air contains this moisture up to its maximum capacity at a certain temperature, the air is said to be saturated which means at this point the air is not able to hold any more moisture content. The temperature at which the air gets saturated where it does not have any additional capacity to hold more moisture is known as the dew point. If we talk about the difference between relative humidity and dew point, the former is the concept that defines the presence of the water content in the air with respect to the temperature whereas the latter one is the point of temperature where the air gets saturated. On the other hand, the air gets saturated when relative humidity reaches 100% which shows that now the air at a particular temperature does not have more capacity to hold the water content and this saturated air leads to the formation of the clouds which leads to various forms of precipitation. Thus, there is a direct relation between the relative humidity as well as the dew point.

At the dew point, it becomes difficult for the air to cool even more and it cannot hold more water content in the form of gas, thus it becomes necessary to come down in the form of droplets of precipitation. Usually, the higher dew point leads to having a higher moisture content in the air, which shows that it will be comfortable only when it flows out. Sometimes, if we talk about relative humidity, it can be misleading as well. If a region has a temperature of 40Â° with a dew point of 40 will lead to 100% relative humidity whereas, on the other hand, a region with a temperature of 80Â° with a dew point of 60 will lead to having 50% humidity. But in both cases, the regions with 80Â° temperature will feel more humidity than the other one which is having 100% relative humidity.

### Relation Between Dew Point and Moisture Content

If we talk about the dew point, it is the point where the air gets saturated at a certain level. Usually, it is saturated at 100% relative Humidity whereas moisture is the water content present in the air. When the air gets saturated, it leads to the formation of the clouds and then further leads to precipitation. When we move towards poles, the frequency of the cloud formation increases but there is no high rainfall whereas at the equator, cloud formation does not occur so frequently but still there is heavy rainfall. In the colder areas, the air is almost saturated, thus frequent clouds form but in other warm areas air gets saturated only after reaching a certain height. This shows that it is not possible that rising air will get additional moisture from the troposphere. Air is not getting saturated because of getting additional moisture but because of the decreasing capacity of moisture. Thus, the frequency of the formation of clouds does not mean it will have more moisture and will lead to heavy precipitation or neither it means that saturated air will surely lead to having extra moisture and will lead to heavy rainfall.

### Conclusion

Thus, in the end, we can conclude that temperature and humidity are one of the most important and basic concepts of climatology where one is determining the heat level of the object or any area whereas the other defines the moisture content in the air. In this article, we have covered the relation between relative humidity and temperature, along with the relation between humidity and temperature formula and other concepts such as absolute and relative humidity, dew point, etc. This topic will help you to get one of the most common, basic as well as important concepts of the climatology of Geography which helps in increasing your daily life knowledge.

FAQ (Frequently Asked Questions)

1. What is the Relationship Between Air Temperature and Relative Humidity?

Answer. Both these phenomena are related to climatology and are directly related. They both influence the weather conditions of the regions. With humidity, the temperature of the region feels hotter. It affects the flora, fauna and humans as well. On the other hand, they are inversely proportional to each other. When the temperature rises, humidity decreases and when temperature decreases, humidity increases.Â

2. Difference Between Relative Humidity and Dew Point.

Answer. Dew point is the point where the air gets saturated at a specific temperature. When air does not have any more capacity to hold water content, it is called a saturation point. If we talk about the relative humidity, it tells us how much water content is present in the air with respect to the particular temperature at that place. When relative humidity reaches 100%, the air does not have more capacity to hold additional water content and is called as saturated.Â

3. Difference Between Absolute and Relative Humidity.

Answer. The difference between absolute and relative humidity is the temperature. The former tells the moisture content in the air without any effect of temperature but latter tells the moisture content in the air with regard to the temperature. The former is expressed in g/m3 means moisture in grams per cubic meter of air whereas the latter is expressed in percentage form. The former does not give an exact idea of humidity present in the air because it does not tell us about the air saturation whereas the latter tells us where does air get saturated and how it leads to the formation of clouds.Â
