Westerly wind prevailed throughout the boundary layer. The comprehensive evaluation to satellite precipitation products has significant implications.
At the same time, a mesoscale synoptic system, typhoon Haitang, was located at southeast of Taiwan. The dynamic process of this ozone episode was studied using an integrated numerical model, that is, a mesoscale meteorological model and Community Multiscale Air Quality CMAQ model.
Model performance has been evaluated using both ground-based meteorological and air quality observations.
Meanwhile, Habib et al. Acknowledgments The authors would like to express their gratitude to the Hong Kong Environmental Protection Agency and Hong Kong observatory for providing meteorological and air pollutant data.
However, the photochemical smog 17 July to 20 July induced by typhoon Haitang was associated with moderate wind speed and nonstagnant meteorological conditions. While the government has passed laws and policies for these purposes, the regulations are not heavily enforced.
Destructive winds of 50 knots are no longer occurring. The processes analyzed include horizontal advection and diffusion the sum is called horizontal transportvertical diffusion and transport the sum is called vertical transportchemical reactions, emissions, dry and wet deposition, and cloud process, which includes aqueous chemistry, scavenging, and cloud vertical mixing.
This recirculation allowed primary and secondary pollutants to accumulate. Make final check of food and other supplies. Both events are rare, but extremely destructive.
Sunny and hot weather persisted over the ensuing ten days. Figures 7 a — 7 d show the continuous time from The dashed rectangle is demarcating the ozone episode days from nonepisode days.
Climate change has also increased the frequency and severity of natural disasters. This study intends to investigate the error characteristics of the CMPA estimate on typhoon storms through comprehensive assessment, such as quantifying total rain depth, rainfall hyetograph, spatiotemporal pattern and storm evolutions, and so on.
High surface ozone concentrations exceeding ppb were observed in the afternoon from 17 to 20 July. The induced meter wind flow in Hong Kong was mainly westerly with a moderate speed. Destructive winds of 50 knots or greater are possible within 72 hours. Actual winds of 50 knots or greater.
Usually, an anticyclone in the upper layers of the troposphere above the storm must be present as well—for extremely low surface pressures to develop, air must be rising very rapidly in the eyewall of the storm, and an upper-level anticyclone helps channel this air away from the cyclone efficiently.
In the past two decades, air pollutant emissions from motor vehicles, power plants, industry, and infrastructure construction have been increasing due to rapid economic development.
According to the weather report by the Hong Kong observatory, sunny weather first started on 10 July when a ridge of high pressure was established over the coast of south China.
Outer rainbands can organize into an outer ring of thunderstorms that slowly moves inward, which is believed to rob the primary eyewall of moisture and angular momentum. By inspecting weather charts, Wang and Kwok [ 7 ] also found out that severe and prolonged pollution episodes were induced by a quasistationary tropical cyclone in the East China Sea that caused air subsidence and stagnation over the PRD.Typhoon-related Leptospirosis and Melioidosis, Taiwan, Hsun-Pi Su, Ta-Chien Chan, and Chao-Chin Chang More in-depth studies need to be conducted.
Efforts need to be taken in advance to prevent possible transmission of these infectious diseases after typhoons.
Acknowledgment. This report reflects on 19 cases of humanitarian shelter implemented in the aftermath of Typhoon Haiyan in the Philippines.
Lessons learned, barriers to implementation, and innovative methods are presented across projects in Cebu, Leyte, and Eastern. Methods.
To analyze typhoon-induced hazards, which are one of the significant disasters of East Asian countries, a statistical analysis using the extreme value theory, which is a method for estimating the annual exceedance frequency of a rare event, was conducted for an estimation of the occurrence intervals or hazard levels.
Driver Expectations When Navigating Complex Interchanges Chapter 2. Task 2-Literature Review. The objective of task 2 was to conduct a literature review of prior work on driver navigation problems and driver expectations at interchanges and.
The northward shift of the typhoon track tends to be associated with typhoon-enhancing environmental conditions over the western North Pacific, namely, the weakening of the western North Pacific subtropical high, the strengthening of the Asian summer monsoon trough, and the enhanced positive vorticity anomalies in the lower troposphere.
Typhoon-related climate studies often focus on the var- iation of typhoon intensity, frequency, and track in mul- titemporal scales ranging from intraseasonal to inter.Download
