This EnKF vortex initialization methodology is now applied to studies of different issues on different typhoons [e. This method will continue to shed light on the scientific understanding of typhoons, and most importantly to improve typhoon forecasting. A new sensitivity analysis method has been proposed for the ensemble prediction system in which a TC-position is taken as a metric. Ito and Wu , JAS. A new study on the role of the diabatic process in affecting eyewall evolution has been carried out in Wu et al. This study points out the deficiency of the dry barotropic model in describing detailed eyewall dynamical processes, and provides new insights into the eyewall physics.?
Idealized numerical experiments have been conducted Wei and Wu to highlight the role of moist heating in affecting the eyewall dynamics.? It is shown that when the diabatic heating and 3-D flows are taken into account, the resultant vortex evolution paths are very different from those in the 2-D barotropic model. In Wu et al. A deeper understanding of the underlying dynamics of SEF has been obtained based on recently developed insights on the axisymmetric dynamics of tropical cyclone intensification.?
This is an attractive paradigm on the physical grounds because of its simplicity and consistency with the 3-D numerical simulations presented.? Application of the two spin-up mechanisms set the scene for a progressive boundary layer control pathway to SEF.? The unbalanced boundary layer response to an expanding swirling wind field is an important mechanism for concentrating and sustaining deep convection in a narrow supergradient-wind zone in the outer-core region of a mature TC.? The findings point to a sequence of structural changes in the outer-core region of a mature TC, which culminates in the formation of a secondary eyewall.
A series of follow-up works is recently proposed to provide complete dynamical analyses of SEF.? We believe this series of studies will further bring considerable dynamical insights into SEF, and thus will reveal the critical physical processes that need to be adequately represented in a numerical model, which will in turn facilitate further understanding of TC dynamics and improvement in typhoon forecasting.? In all, the works of Wu et al. Understanding how the Taiwan terrain affects the track, intensity, wind structure, and precipitation distribution is one of my key research thrusts.
A paper studying the effects of the terrain on the eyewall dynamics and Vortex-Rossby waves of landfalling typhoons Wu et al. The role of the adiabatic process in affecting the eyewall evolution has also been examined in details in another paper Wu et al. This study points out the deficiency of the dry barotropic model in describing the detailed eyewall dynamical processes, and provides new insights into the eyewall physics that is consistent with the new theories as described in Montgomery et al.
The role of terrain in affecting the looping motion of typhoons channel effect near the terrain has been demonstrated in Jain and Wu MWR.? This study indicates how the terrain-induced channel effect leads to the unusual looping motion of Typhoon Haitang.
In this way, the painting also gives out a conflicting force. She wanted to push aside the conventions and limitations traditional Chinese ink painting placed on form, techniques and materials, and focus instead on experimenting and innovating in terms of style and artistic vocabulary. When one basin is active, the other is normally quiet, and vice versa. She demonstrates mastery of brush and ink. Within the northwestern Pacific there are no official typhoon seasons as tropical cyclones form throughout the year. The findings point to a sequence of structural changes in the outer-core region of a mature TC, which culminates in the formation of a secondary eyewall.

The looping motion of typhoons has been further investigated in Huang et al. The study shows consistent results with Jian and Wu that the distinct southward track deflection prior to landfall can be attributed to the northerly jet enhanced by the channel effect at the narrow pathway between the high topography of Taiwan and the eyewall with high inertial stability of Krosa. Such findings in Huang et al.
This series of research provides clear insights into the physics of typhoon-terrain interactions, which is also observed in many similar typhoon events near Taiwan.? A further study with idealized experiments under a wider spectrum of flow regimes has been ongoing to more thoroughly investigate the dynamics of such processes.? New flow regimes have also been identified Li and Wu One of the flagship studies my team has conducted on this issue is rainfall associated with TC-monsoon-terrain interaction. A heavy rainfall event in the Taiwan area associated with the interaction between Typhoon Babs and the East Asia winter monsoon is studied Wu et al.
Such heavy rainfall was caused by the joint convergent flow associated with the outer circulation of typhoons and the strengthening northeasterly monsoon in late typhoon season, even though Babs remained distant from Taiwan when it moved through the island of Luzon in the Philippines and stayed over the south.? It is shown that the terrain plays a key role in changing the low-level convergence pattern between typhoon circulation and monsoonal northeasterlies. This is the first paper published in an international SCI journal that discusses the rainfall mechanism associated with the TC-winter monsoon-terrain interaction, which is well illustrated in the schematic diagrams of the paper Wu et al.
Based on the EnKF data assimilation Wu et al. Futhermore, the 28 ensemble members provide abundant information on their spread and other statistics, which reveal the usefulness of the ensemble simulation for the quantitative precipitation forecast.? It is also suggested that the ensemble simulations with coherent high model and terrain resolutions are valuable in assessing the issue of terrain-induced heavy rainfall, one of the most critical forecast issues in Taiwan.?
The submitted names are arranged into five lists, and each list is cycled with each year. Unlike tropical cyclones in other parts of the world, typhoons are not named after people. Instead, they generally refer to animals, flowers, astrological signs, and a few personal names. Storms that cross the date line from the central Pacific retain their original name, but the designation of hurricane becomes typhoon. In Japan, people use the numerical designation of typhoons according to the sequence of their occurrence in the calendar year.
Only 15 seasons had 30 or more storms developing since reliable records began. In the Philippines, the most active season, since , for tropical cyclone strikes was when nineteen tropical cyclones moved through the country. The rainfall in Pingtung County reached 2, millimeters From Wikipedia, the free encyclopedia. This article is about Northwestern Pacific tropical cyclones. For other uses, see Typhoon disambiguation. For other areas in which tropical cyclones occur, see Tropical cyclone basins. F1 What regions around the globe have tropical cyclones and who is responsible for forecasting there?

The architecture of ideology: With this background Lee developed a talent for ink and wash. There she trained in multiple styles of art, even studying oil painting under Lin Kegung for several years. She started to take part in various artistic activities. She started to explore modern ink and wash painting. Many major artists of the time working in modern ink and wash were members of the Chinese Ink and Wash Painting Society. In Lee decided to focus on ink and wash.
She experimented with a number of different techniques and styles. She developed a lyrical abstract ink and wash style, and her work became more refined over time as she gained experience. In Eye of Typhoon , Lee Chung-chung uses two thick masses of ink on the top and the lower left, lighter ink and wash, as well as blank space to create a dynamic composition. It seems that an eye of a typhoon is moving around in circles on the canvas.
