Cyclones and anticyclones are classified as secondary atmospheric circulations. While “primary” circulations (like the Hadley Cell) are global and permanent, secondary circulations are smaller, regional and temporary. They are the individual high and low-pressure systems that move across the planet, ...
The “Limb” of the Earth is the visual edge of the planet’s atmosphere against the blackness of space as seen from an orbiting satellite or the moon. It appears as a thin, glowing blue arc. This perspective allows scientists to ...
The mesopause is the boundary layer between the mesosphere and the thermosphere. It is notable for being the coldest place in Earth’s atmosphere, with temperatures dipping as low as -100°C. This transition zone marks the point where the temperature stops ...
A pyranometer is a sensor designed to measure the total solar irradiance on a flat surface. It captures radiation from the entire hemisphere (the whole sky) and is used in meteorology, climatology and solar energy research. It helps scientists understand ...
