J. “Statistical Analysis and Updated Clima-tology of Explosive Cyclones. After confirming that the WRF model reproduces the synoptic environments and main features of the event well, the favorable environmental conditions for the rapid development of the cyclone are analyzed, and the explosive development mechanisms of the cyclone are investigated with perturbation potential vorticity (PV) fields.
 The extratropical upper troposphere and lower stratosphere (Ex‐UTLS) is a transition region between the stratosphere and the troposphere. The Ex‐UTLS includes the tropopause, a strong static stability gradient and dynamic barrier to transport. The barrier is reflected in tracer by: The analysis above indicates that the mechanism whereby the land surface thermal anomaly affects the cyclone activity is as follows: Land surface warming in the middle latitude over East Asia tends to decrease the meridional gradient of surface soil temperature in the key area of cyclone activity, which further reduces the atmospheric Author: Haishan Chen, Wanxin Zhan, Botao Zhou, Fanda Teng, Jie Zhang, Yang Zhou.
Forecasts of rapid intensification (RI) within tropical cyclones continue to be a major challenge, primarily due to difficulty in determining the processes that distinguish RI and non-RI storms. In this study, the aim was to identify the most important RI/non-RI discriminatory variables in the North Atlantic basin, not only by level, but also spatial location relative to the tropical cyclone Cited by: 1.

The phenomenon of the rapid growth and development of an extratropical cyclone over the east coast of the United States (the Carolinas storm of March ) is studied through a linear stability analysis. Analyses of the cyclone structure suggest barotropic and baroclinic insta-bilities may be important.
A linear stability model is used. A linear stability analysis of the rapid development of an extratropical cyclone. By Raymond F. Toll Get PDF (6 MB)Author: Raymond F. Toll. For real hurricanes the coefficients A, B, and C can have complicated spatial distributions [e.g., Fig. 6 of Holland and Merrill () illustrates the radial and vertical variations of inertial stability and static stability computed from their composite tropical cyclone], which would preclude analytical solution of obtain analytical solutions we shall consider an idealized vortex Cited by: In an analysis of what has been referred to as The Storm of the Century, Kocin et al.
() described the widespread heavy snowfall, coastal flooding, squall lines, thunderstorms and tornadoes associated with an extratropical cyclone that developed and progressed along the southern and eastern coasts of the United States between the 12 and 14 March, Debate continues as to whether the mesoscale phenomena associated with mid-latitude cyclones.
Extratropical cyclones over the North Atlantic and Europe are notorious for causing large damage to property and loss of life. For example, these storms accounted for over 10% of the total insured losses of the top 40 global natural and man-made catastrophes over the period from to (Enz et al.

Occasionally, an extratropical cyclone can penetrate the tropics, lose its frontal features, develop convection near the center of the storm, and Author: Hai Lin, Jorgen Frederiksen, David M.

Extratropical Cyclone –a cyclonic storm deriving its energy primarily from the horizontal temperature gradient that exists In the midlatitudes (a.k.a.
midlatitude, baroclinic, or frontal cyclone) Variants–Polar lows and Medicanes, which typically are accompanied by upper-level troughs but develop tropical-cyclone. Interannual variability of cyclones that are generated over the eastern Asian continent and passed over the Yellow, Bohai, and East China seas (YBE cyclones) in spring is analyzed using reanalysis datasets for the period of – Possible causes for the variability are also discussed.
Results show that the number of YBE cyclones exhibits significant interannual variability with a period Cited by: 1. Polar Jet and Extratropical Cyclones • Extratropical cyclones are low pressure centers at the surface; thus, upper-level divergence is needed to maintain the surface lows • Generally, there is divergence aloft downwind of an upper level trough to the ridge – a prime location for extratropical cyclone development.

determining the rapid development, since the NON cy-clone, having an initial intensity and a track similar to the NOS cyclone’s, does not exhibit such a deepening tendency.
In particular, the more rapid deepening ten-dency also occurs in the absence of the diabatic heating, as can be seen by comparing the two dry runs between CTLD and NOSD. The cyclone routes were independent of the global flow pattern in the interannual variability, while cyclone growth closely agreed with linear baroclinic theory.
The scale of a typical extratropical cyclone may be several thousands of kilometers, but the Bergen school recognized and utilized that the extreme weather of the cyclone and its most dynamically active regions were confined to certain lines of discontinuity—the : Thor Erik Nordeng.
Major storm systems over Europe frequently have a tropical origin. This paper analyses the characteristics and dynamics of such cyclones in the observational record, using MERRA reanalysis data for the period By stratifying the cyclones along three key phases of their development (tropical phase, extratropical transition and final re-intensification), we identify four radically Cited by: 2.The term "cyclone" applies to numerous types of low pressure areas, one of which is the extratropical descriptor extratropical signifies that this type of cyclone generally occurs outside the tropics and in the middle latitudes of Earth between 30° and 60° latitude.
They are termed mid-latitude cyclones if they form within those latitudes, or post-tropical cyclones if a tropical.
