Relative humidity does not necessarily always increase with increasing air temperature. In fact, the relationship between air temperature and relative humidity is more complex and depends on the amount of moisture present in the air. Relative humidity (RH) is a measure of how much moisture the air holds compared to the maximum amount it could hold at a given temperature. It is expressed as a percentage.

The relationship between temperature and relative humidity can be understood through the concept of the dew point temperature. The dew point temperature is the temperature at which air becomes saturated with moisture, leading to the formation of dew or fog. Here's how these factors are interconnected:

In summary, relative humidity does not always increase with increasing air temperature. It depends on whether the amount of moisture in the air remains constant. Cooling unsaturated air to its dew point temperature causes saturation, leading to a relative humidity of 100% and the potential for condensation to occur.

It's important to note that weather variables, such as temperature and humidity, are interrelated and influence each other in complex ways. Understanding these relationships is essential for meteorologists and climate scientists to predict weather patterns and phenomena accurately.

Now, with the increase in temperature the capacity of the atmosphere to hold the water vapour or moisture increases, thus decreases the relative humidity. Hence, with an increase in the temperature of air, the relative humidity will decrease even if the moisture content remains the same. The total amount of water vapor that the air can carry depends on the temperature of the air. So, if the air chills the total amount of water vapor, it can hold drops, and hence the relative humidity rises. The value of absolute humidity differs with air temperature and pressure changes if the volume is not fixed. It is also affected by the water distribution on the Earth and seasonal changes. As it is the measure of absolute moisture in the air, it relatively remains constant. Warm air can possess more water vapor (moisture) than cold air, so with the same amount of absolute/specific humidity, air will have a higher relative humidity if the air is cooler, and a lower relative humidity if the air is warmer. The relation between humidity and temperature is inversely proportional. If temperature increases, it will reduce relative humidity; thus, the air will become drier. When the temperature decreases, the air will become wetter; therefore, the relative humidity will increase. The relation between humidity and temperature is inversely proportional. If temperature increases, it will reduce relative humidity; thus, the air will become drier. When the temperature decreases, the air will become wetter; therefore, the relative humidity will increase. However, relative humidity is dependent on air temperature, too. If the water vapour content stays the same and the temperature drops, the relative humidity increases. If the water vapour content stays the same and the temperature rises, the relative humidity decreases. Relative humidity (RH) is a measure of the moisture in the air, compared to the potential saturation level. Warmer air can hold more moisture. When you approach 100% humidity, the air moisture condenses this is called the dew point. Air temperature is a measure of the heat. Dew point temperature is never greater than the air temperature. Therefore, if the air cools, moisture must be removed from the air and this is accomplished through condensation. This process results in the formation of tiny water droplets that can lead to the development of fog, frost, clouds, or even precipitation. When cooled more, it condenses into droplets that fall to earth as precipitation, as rain, snow, sleet or hail. Precipitation takes one of two paths once on the ground. It runs over the surface into rivers, lakes or the ocean, and becomes surface water, or it soaks into the earth and becomes groundwater.
