India Meteorological Department (IMD) uses temperature data from surface observatories to track heat waves. IMD also uses various numerical weather prediction models to track and predict occurrence and intensity of Heat Waves. The following criteria are used for defining severity of the heat wave: When normal Tmax is less than or equal to 40°C and … Read more DMPQ-What is a heat wave and what might be the reasons for high frequency of heat waves?

Normally, temperature decreases with increase in elevation. It is called normal lapse rate. At times, the situations is reversed and the normal lapse rate is inverted. It is called Inversion of temperature. Inversion is usually of short duration but quite common nonetheless. A long winter night with clear skies and still air is ideal situation … Read more DMPQ- What is temperature inversion and how does it effect atmosphere?

Composite lava are highly viscous with a high melting point. They are light colored and have low density, and have a high percentage of silica.
