What is a snow bomb?
The Met Office explain: A 'weather bomb' is an unofficial term for a low pressure system whose central pressure falls 24 millibars in 24 hours in a process known as explosive cyclogenesis.
Is bomb cyclone a real term?
Explosive cyclogenesis (also referred to as a weather bomb, meteorological bomb, explosive development, bomb cyclone or bombogenesis) is the rapid deepening of an extratropical cyclonic low-pressure area.
What is meteorological bomb?
Storms that intensify very quickly are called “bomb cyclones”, “meteorological bombs”, or “bombs”. ... With strong forcing in place, the air at the center of the storm rises rapidly, causing a rapid decrease in pressure.
What is a water bomb weather?
A review of terminology for extreme rain events and the media-effect. The term has, today, become established in Italy to qualify a cloudburst that is newsworthy. ... That is, it bursts over a populated area within the newspaper catchment to cause localized damage.
What has to happen for a weather bomb to take place?
When storms quickly intensify and pressure rapidly drops in the centre - by 24millibars in a 24-hour period - this is known as a weather bomb. The process is also known as explosive cyclogenesis.
What happens during a bomb cyclone?
A bomb cyclone is simply a storm that intensifies very rapidly. Bomb cyclones form when air near Earth's surface rises quickly in the atmosphere, triggering a sudden drop in barometric pressure — at least 24 millibars within 24 hours. As the air rises, wind spirals in at the base of the storm.
How common are bomb cyclones?
Bomb cyclones are more common than most people realize. Some 40 to 50 storms in the Northern Hemisphere undergo "bombogenesis" each year, according to meteorologist Ryan Maue. That includes some of the nor'easters that rage across the northeastern US in the winter.
What does Cyclogenesis mean?
Cyclogenesis is defined as any development or strengthening of cyclonic circulation in the atmosphere.
What are the six stages of cyclogenesis?
Stages of Cyclogenesis
- Stationary Stage. The first stage of cyclogenesis, the stationary stage, is named so due to the presence of a stationary front. ...
- Wave Stage. ...
- Open Stage. ...
- Occluded Stage. ...
- Dissipation Stage.
What kind of air mass is most likely to cause thunderstorms?
maritime tropical air mass
Where do you expect to see cyclogenesis often occurs?
Cyclogenesis most often occurs along this polar front, especially underneath areas located just downstream of 500 mb troughs because in these areas upper tropospheric divergence is occurring (see polar front, cyclogenesis picture).
What causes Cyclogenesis?
Cyclogenesis, in meteorology, the process of extratropical cyclone development and intensification. Cyclogenesis is initiated by a disturbance occurring along a stationary or very slow-moving front between cold and warm air. This disturbance distorts the front into the wavelike configuration.
Why will mid-latitude cyclogenesis not happen in systems that are vertically upright?
When a mid-latitude cyclone becomes vertically stacked, meaning the surface low pressure system is no longer ahead of the upper-level divergence, it will begin to weaken (and become occluded).
What is a Lee low?
A lee-side trough (low) is commonly taught as caused by the stretching of a column of air as it descends on the lee-ward side of highly elevated terrain such as the Rocky Mountains. ... A downslope flow will be most intense if the windflow is perpendicular to the mountain range and the winds have a high velocity.
What is the lee of a mountain?
The term leeward, or lee, refers to slopes that are oriented away from the wind. If winds are strong enough, snow from windward slopes can be redistributed or blown to leeward areas, causing them to become loaded. Wind slabs often form on lee aspects as a result of this wind transport.

What is Lee effect lifting?
In meteorology, lee waves are atmospheric stationary waves. ... They are periodic changes of atmospheric pressure, temperature and orthometric height in a current of air caused by vertical displacement, for example orographic lift when the wind blows over a mountain or mountain range.
What is organic lifting?
When wind hits a mountain, it is forced to rise. This rising motion helps the air cool and moisture condenses into snow. Orographic lift is the technical term for terrain forcing air to rise. ... Rising air is a requirement for precipitation. When air rises, it expands due to lower pressure.
What is frontal lifting?
- Frontal Lifting is when less dense warm air is forced to rise over cooler, denser air as a weather fronts move. Most common in winter. - Convection is when solar energy passes through the atmosphere and heats the surface, where the air becomes less dense than the air around it, making it rise.
