Introduction to humidity, relative humidity, and dew point

What is humidity? Humidity is the amount of water vapour present in the atmosphere. The amount of humidity depends on air temperature and pressure, typically it is very between 2-5%. Th 99 percent of the water vapour resides within the troposphere. Types of humidity  There are three types of humidity:  1. Absolute humidity  2. Specific …

How do thunderstorms form?

Thunderstorms are very common. A thunderstorm is a storm causing lightning and thundering. We can easily recognize thunderstorms by huge clouds, lightning, torrential rain, and stormy winds. Such type of thunderstorm weather brings the life-giving rains. But how does such weather form where rain arrives with thunder and lightning? Let’s see. How do thunderstorms form? …

What is atmospheric pressure and how it is measured?

Atmospheric pressure is an important characteristic of the atmosphere. Wind and other weather phenomena occur due to changes in atmospheric pressure. In physics, the pressure is the perpendicular force on the object. What is atmospheric pressure? Our atmosphere is composed of air. The molecules of gases and water vapor constitute the air. Due to gravitational …

Troposphere | Introduction, temperature, and composition

The troposphere is the lowest layer of the atmosphere. The troposphere extends from sea level to altitude of 18 km. Altitude is the height measured from sea level. However, the upper boundary of the troposphere varies with latitude and season. The upper boundary of the troposphere is called the tropopause. The temperature in the troposphere …
