Definition of mesocyclone in US English: mesocyclonenoun ˌmēzə-ˌmēzə- Meteorology A cyclonic air mass associated with a supercell; its presence is a condition for a tornado warning. Example sentencesExamples - Some of the rotational velocities may have been underestimated because of the small width of the vortex, supported by large spectrum widths associated with mesocyclones some distance from the radar.
- This helicity value was classified as a strong mesocyclone environment according to Davies-Jones.
- Various different temperatures and wind interactions at different altitudes can cause a rotating updraft called a mesocyclone.
- One of the major differences of super cells compared to that of single-cell and multi-cells storms is that, the super cell contains a viscous rotating updraft, this rotational updraft is known as a mesocyclone.
- Figure 2 shows the trend of average lowest altitude diameter of the mesocyclone from T - 5 to T + 1.
- The frequency shift is then converted to wind velocity, yielding a small region of rapidly changing wind direction, a characteristic rotational wind shear signature of the mesocyclone indicating a tornadic circulation.
- A survey of mesocyclones near the Antarctic Peninsula using digital satellite imagery collected at Palmer Station
- Mesolow should not be confused with mesocyclone, which is a storm-scale phenomenon.
- The best view of a mesocyclone is normally from a location east of the updraft, looking west.
- These kinds of mesocyclones are also rare, only occurring with landfalling tropical systems.
- This is true even though some recent observations found that the mesocyclone gust front structures are not strictly low-level phenomena, but instead, extend through a considerable depth of the storm.
- Huaqing applied this technique to radar data of five mesocyclones, three of which spawned tornadoes.
- Should the proportion of tornadic mesocyclones go down to 20% or so, as it now appears it might, this problem is correspondingly exacerbated.
- It is worth to mention that the axisymmetric circulation characteristics of the mesocyclone at its mature stage resemble a feature very similar to that observed in a mature typhoon.
- To do so, it will first be necessary to examine to what extent mesocyclones appear in high
- If the thunderstorm is moving rapidly toward or away from you, the mesocyclone may be harder to detect.
- Thunderstorms containing mesocyclones are known as supercells, and sometimes produce destructive tornadoes.
- Two rotating wall clouds revealed twin low-level mesocyclones on the SW side of a classic, cyclic supercell.
