Study Notes
- A low-pressure area is a region where the atmospheric pressure is lower than surrounding locations.
- Low-pressure areas are associated with inclement weather, while high-pressure areas are associated with lighter winds and clear skies.
- Low-pressure systems form under areas of wind divergence that occur in the upper levels of the atmosphere.
- Thermal lows form due to localized heating caused by greater solar incidence over deserts and other land masses.
- Large-scale thermal lows over continents help drive monsoon circulations.
- Atmospheric lift will generally produce cloud cover through adiabatic cooling once the air temperature drops below the dew point as it rises.
- The stronger the area of low pressure, the stronger the winds experienced in its vicinity.
- Cyclogenesis is the development and strengthening of cyclonic circulations or low-pressure areas within the atmosphere.
- Polar lows are small-scale, short-lived atmospheric low-pressure systems that occur over the ocean areas poleward of the main polar front in both the Northern and Southern Hemispheres.
- Monsoons resemble sea and land breezes, terms usually referring to the localized, diurnal (daily) cycle of circulation near coastlines everywhere, but they are much larger in scale - also stronger and seasonal.
- Monsoon troughs form as part of Hadley cell circulation
- Large-scale thermal lows over continents create pressure gradients driving monsoon circulations
- Many rainforests are associated with climatological low-pressure systems
- Tropical cyclones need to form more than 555 km poleward of 5th parallel north and south
- Tropical cyclone activity peaks in late summer globally
- Western Pacific Ocean is the most active tropical cyclone basin on Earth
- Wind flows from high-pressure to low-pressure areas due to density differences
- Coriolis force causes winds around low-pressure areas to have counter-clockwise circulation in the northern hemisphere and clockwise circulation in the southern hemisphere
- Tornadoes may be influenced by Coriolis force when arising from a low-pressure system
- November is the only month that activity in all tropical cyclone basins is possible
