The Evolution and Role of Midtropospheric Cyclonic Vortex in the Formation of Super Typhoon Nepartak (2016)

<p>The present laboratory study is focused on the role of convective rolls in enhancement of the heat flux from the sea and triggering of the process of rapid intensification of tropical cyclones. The appearance of coherent convective structures such as thermals and rolls are registered by different optical techniques and temperature measurements. Two-dimensional velocity fields are used for the study of the structure and characteristics of the flow. The heat flux from the heating plate to the fluid is measured directly. Obtained results clearly show that rapid intensification of a laboratory analog of a tropical cyclone is tightly linked with the heat transfer process in the boundary layer. Formation of secondary convective structures strongly increases the heat transfer and intensity of convective circulation. Intensity of radial inflow is a crucial aspect for the intensification of cyclonic vortex, hence rapid variation of the heat transfer is a factor that has a substantial influence on the dynamics of a laboratory vortex. </p>

With the remarkable intensity of 170 knots, Typhoon Haiyan starts as a tropical depression on November 3 and develops to the peak as super tropical cyclone (TC) on November 7 in 2013. This intensity makes Haiyan one of the strongest TCs record ever observed and 35 knots higher than the maximum of the existing highest category. Haiyan originated from the eastern part of the Northwest Pacific Warm Pool and moved westward over warm water with a thick barrier layer (BL). The BL reduced the vertical mixing and entrainment caused by Haiyan and prevented the cold thermocline water into the mixed layer (ML). As a result, sea temperature cooling associated with wind stirring was suppressed. Relative high sea surface temperature (SST) kept fueling Haiyan via latent heat flux release, which favored the rapid development of a “Category 6” super typhoon.

High Tidal Level

This paper aims to the inundated conditions which probably occur in the macro-tidal estuary where the floodplains are lower than the high tidal level. A high Precision two-dimensional numerical model is developed to simulate the inundated degree introduced by storm surges taking the Qiantangjiang estuary coastal area as an example. Except for the sea area, both sides of the floodplains are included in the calculation scope. Meanwhile, the secondary dikes owing to the reclamation projects and some roads which have the effect on tide resistance are considered. In this article, the front dikes damaged scale is determined by Interior Wave Model Experiment[3], Safety Assessment of the Front Dikes’ Ultimate Defense Capability[11]. Using the model, this paper simulated inundated conditions under the typical super typhoon which takes Typhoon No.5612, the most intense typhoon landed in china since 1949, as the controlling conditions. According to the calculated results, this paper analyzed the effects of joint multi-line defense (the secondary dikes and roads) behind the front dikes and obtained action sphere and role of each defense. These results can be applied to direct the defense of storm surges over designed standard occurring in the macro-tidal estuary.

Descriptive Method

The presented paper focuses on the role of architecture in post-disaster humanitarian efforts particularly on the return to normalcy and sustainable recovery. Two major approaches were introduce, ‘Architecture of empowerment’ and ‘Strengths-based approach’ to analyze two cases of post disaster rebuilding projects employed in Batug, Leyte Philippines after super-typhoon Haiyan. The objective of the paper was to formulate a framework for post-disaster humanitarian efforts in order to achieve sustainable recovery. Another objective was to look at the interrelationship of the humanitarian architecture and psychosocial intervention or the journey to normalcy. Key Informant Interviews with locals, observers and participants of the shelter project, were used to gather information for both projects. Qualitative analysis and descriptive method were used for the interpretation the gathered data. In the end, a framework was formulated which points out that the integration with the roles of humanitarian architecture ( provider, supporter and catalyst) with strength-based approaches in post-disaster efforts factors of resources, competencies and sustainable recovery and the interplay of all these factors are the vital elements in order to have successful rebuilding projects after disasters.

AbstractWhitehouse adapts insights from evolutionary anthropology to interpret extreme self-sacrifice through the concept of identity fusion. The model neglects the role of normative systems in shaping behaviors, especially in relation to violent extremism. In peaceful groups, increasing fusion will actually decrease extremism. Groups collectively appraise threats and opportunities, actively debate action options, and rarely choose violence toward self or others.
