Explain the terms convection and conduction? What will happen to the convection currents in the mantle if the Earth's interior eventually cools down? What are the convective and radiative zones? What do you understand by the free convection boundary layer and how does it affect heat transfer?
How does wind erosion gets its energy? Why is wind speed important in atmospheric science? How do air currents affect climate? How are air currents affected by the Earth's spin? How can air masses affect air pollution? How does bleed air affect jet engine performance?
In a total solar eclipse, the Moon completely covers the Sun, revealing the Sun's corona. An annular eclipse occurs when the Moon is farther from the Earth, resulting in a ring-like appearance of the Sun around the Moon's silhouette. Does a solar eclipse affect humans? A solar eclipse ...
Most of the movements of air currents on a global scale happen in the Earth's upper atmosphere. As the sun-warmed air rises, it diverges in the troposphere and moves toward the Earth's poles in several giant loops called circulation and/orconvection cells. ...
Launched in 2010, the Solar Dynamics Observatory is a mission to study the aspects of the Sun that directly affect our life on Earth: solar wind, solar flares, and other outbursts of energy. STEREO, for its part, is a pair of satellites that gave us stereo vision of the sun in the ...
Earth’s atmosphere where they can cause magnetic storms that disrupt cell phone and radio communication and affect electrical grids. During the 1989 event, the solar max, a power surge triggered by energy from the sun damaged several transformers that were part of the Hydro-Quebec power system....
throw it out completely. Microwaves use radio waves between 300 MHz and 3 GHz. With age, they can leak radiation through the door when it gets old or damaged, according to WHO. If you use a microwave, replace it when needed, or get a convection oven instead. Just make sure to stand ...
Nevertheless, local conditions may affect the impact cases significantly, which needs to be investigated with more sophisticated urban models. 4.1. Implications for the impact cases The results of this research show a stronger decrease of influenza days on the convection-permitting scale under near-...
Because the ocean mixed layer responds so rapidly to surface densification by buoyancy-forced processes, the deepening of the mixed layer can often be estimated successfully using one-dimensional approaches as the nonpenetrative convection equation [Marshall and Schott, 1999]: (2)where the vertical ...
