It helps in forming human comfort products such as air conditioners. It is very important to monitor the moisture around any product or even while construction of the buildings. It helps in animal husbandry and keeping certain foods at a certain point. The temperature feels hotter than it actually is with the presence of more humidity in the air. It helps in weather forecasting as this concept is useful in understanding the rainfall patterns or dew points. It can lead to various effects on various things whereas it can be useful in multiple things which are mentioned below: These two regions show the relation between the relative humidity and temperature where an increase in temperature leads to a decrease in relative humidity and these both are inversely proportional to each other. Suppose, in a particular region where there is a temperature of 30° with a relative humidity of 50% and on another hand, at a different location there is a temperature of 40° with a relative humidity of 33%. When the relative humidity is 100%, it means that it is a saturated air where saturation generally means a point where water vapour present is equal to the capacity and this saturation helps in the formation of clouds on the other hand the temperature at which this air is saturated is known as dew point. Relative Humidity = \ x 100Įxample : Suppose, if there is 100% water vapour present in a piece of air at a certain level, and its capacity of holding water vapour is 200, then according to the above formula, the relative humidity will be 50%. It is basically a ratio of the amount of water vapour present in a particular parcel of the air and the total capacity of the air to hold the water vapour and it is expressed in percentage form with symbol φ or RH. We can calculate the relative humidity with the help of the following formula. RH increases (means the air will become wetter) RH decreases (means the air will become drier) Relationship Between Temperature and Relative Humidity The effect on relative humidity with respect to change in temperature or pressure is mentioned below which shows that there is an inverse relationship between temperature and relative humidity whereas there is a direct relationship between pressure and relative humidity. It is majorly high at midnight and in the early morning and it reduces rapidly after the sun rises and then it is lowest and then again it starts increasing up to midnight. It is always expressed in the form of percentage or can be written as φ or RH. When the humidity percentage reaches 100%, it is called saturation which helps in the formation of the clouds. It is not dependent on the height but on the capacity of the air to hold moisture. The higher percentage of relative humidity in the air says that it is more humid. It is that percentage that specifies how much moisture can be held by air and this moisture can be increased with an increase in the temperature but on the other hand temperature and relative humidity are also inversely proportional. It is basically an amount of water vapour present in the air. In this article, we will be talking about Relative Humidity and its related aspects. It also helps in understanding the relation between temperature and humidity on the basis of its particular type. The difference between the humidity of two regions is generally known as humidity gradient. Humidity after condensation leads to the formation of clouds and these clouds lead to precipitation and this precipitation can occur in any form such as rainfall, snowfall, hailstone, sleet, etc. Humidity basically helps in determining the water vapour in the air ie. You will also learn the relationship of relative humidity with pressure or temperature as well. In this article, we will learn about what is humidity, the difference between the two types of humidity, relative humidity meaning, its formula or percentage and examples, various uses or effects etc. In this article, we will be talking about this concept of Geography or Geophysics ie. These are the basic points of daily weather forecasting and in this relative humidity plays a vital role. You must have heard or checked the weather forecasters saying that there is a relative humidity of this much percentage at a certain region, or there can be chances of a cloud formation or even the chances of rainfall, etc.
