- Pressure= 1000 x (0.5)5.6/5.6
Pressure=500 mb
Pressure=1000 x (0.5)8.85/5.6
Pressure=334.40 mb
Pressure=1000 x (0.5)11.2/5.6

Pressure= 1000 x (0.5)50/5.6
Pressure=2.05 mb
- The temperature of the upper stratosphere is greater than that of the lower stratosphere due to the presence of the ozone layer. It is here where ozone absorbs ultraviolet light, which triggers chemical reactions. These chemical reactions produce heat, a process which is not found in the lower stratosphere.
- Conduction is the transfer of heat through solid objects such as metal and wood when the molecules come in contact. Conversely, convection is the process of the transfer of heat through gases and liquid through the movement of the molecules from place to place. As either of these substances heat up, they rise and then fall when they cool. These processes operate together as conduction transfers heat from the ground into the air then that air rises through convection to push cool air down, restarting the cycle. Radiation differs from both these processes as it involves move energy by electromagnetic waves through empty space.
- As temperature increases, the peak wavelength of an object will decrease. This occurs because the object emits energy. As the energy increases, the waves move faster, creating shorter wavelengths.
- On the winter solstice, the sun displays the greatest range of altitude across the planet. In the North Pole on that day, the sun is at its lowest point in the sky because the Earth is inclined away from the sun at that time. As one travels towards the South Pole, the amount of daylight and the altitude of the sun increase because that hemisphere is tilted towards the sun.
- As radiation travels towards the Earth’s surface, it is absorbed or deflected by gasses in the atmosphere. Due to these processes, the wavelengths that do reach the surface are normally less harmful than that which leaves the sun.
- Radiation moves from areas of surplus to areas of deficit through atmospheric circulation and convection as well as through the movement of ocean currents.
- Hydrostatic equilibrium is the interaction of a pair of forces, namely gravity and pressure gradient force, which maintains Earth’s atmosphere. Gravity works to prevent the atmosphere from collapsing inwards towards the planet’s surface. Pressure gradient force counteracts this by limiting the extent of the atmosphere, creating a contained layer of air.
- In cyclones in the Northern Hemisphere, air moves in a counterclockwise rotation around an area of low pressure. The air in the center also moves upwards, causing an increase in precipitation and storms. In anticyclones, the situation is the reverse. Air moves in a clockwise motion under an area of high pressure. Additionally, in the center, air moves down.
- Geostrophic flow is the movement of air along areas of similar pressure, or isobars due to the Coriolis Effect counteract pressure gradient force. Gradient flows are the movement of air along isobars which are not straight. Like geostrophic flow, they are affected by the Coriolis Effect and pressure gradient force as well as centrifugal forces. These do not occur near Earth’s surface as the moving air has a high pressure, meaning that it is farther away from the Earth’s surface than low pressure air.
