Effects of Dropsonde Data in Field Campaigns on Forecasts of Tropical Cyclones over the Western North Pacific in 2020 and the Role of CNOP Sensitivity

Valuable dropsonde data were obtained from multiple field campaigns targeting tropical cyclones,namely Higos,Nangka,Saudel,and Atsani,over the western North Pacific by the Hong Kong Observatory and Taiwan Central Weather Bureau in 2020.The conditional nonlinear optimal perturbation(CNOP)method has been utilized in real-time to identify the sensitive regions for targeting observations adhering to the procedure of real-time field campaigns for the first time.The observing system experiments were conducted to evaluate the effect of dropsonde data and CNOP sensitivity on TC forecasts in terms of track and intensity,using the Weather Research and Forecasting model.It is shown that the impact of assimilating all dropsonde data on both track and intensity forecasts is case-dependent.However,assimilation using only the dropsonde data inside the sensitive regions displays unanimously positive effects on both the track and intensity forecast,either of which obtains comparable benefits to or greatly reduces deterioration of the skill when assimilating all dropsonde data.Therefore,these results encourage us to further carry out targeting observations for the forecast of tropical cyclones according to CNOP sensitivity.

Then and Now： A Content Analysis of Media Used in the Presidential Election Campaigns of Kennedy and Obama

American campaigning has become increasingly complex as it adjusts to our ever-changing cultural landscape. The use of electronic media in the presidential campaigns of 1960 and 2008 is illustrative of this shift. A content analysis of these two campaigns demonstrates how each applied the newest technologies available at the time to define the candidate＇s image and export the messages to the electorate. Whether it be Kennedy＇s use of television or Obama＇s usage of social media, the role that new media of the day played in both campaigns clearly set the tone for future political campaigns. This examination of the role of media in both elections serves to form a primer for how the successful applications of new media lead to campaign victory. Then and now, the growing influence of new technologies on campaigning makes it necessary to compare and contrast the successful usages and strategies employed. The need for continuing analysis will grow in the coming years.

A Closure Study of Aerosol Hygroscopic Growth Factor during the 2006 Pearl River Delta Campaign

Measurements of aerosol physical, chemical and optical parameters were carried out in Guangzhou, China from 1 July to 31 July 2006 during the Pearl River Delta Campaign. The dry aerosol scattering coefficient was measured using an integrating nephelometer and the aerosol scattering coefficient for wet conditions was determined by subtracting the sum of the aerosol absorption coefficient, gas scattering coefficient and gas absorption coefficient from the atmospheric extinction coefficient. Following this, the aerosol hygroscopic growth factor, f（RH）, was calculated as the ratio of wet and dry aerosol scattering coefficients. Measurements of size-resolved chemical composition, relative humidity （RH）, and published functional relationships between particle chemical composition and water uptake were likewise used to find the aerosol scattering coe？cients in wet and dry conditions using Mie theory for internally- or externally-mixed particle species [（NH_4）_2SO_4, NH_4NO_3, NaCl, POM, EC and residue]. Closure was obtained by comparing the measured f（RH） values from the nephelometer and other in situ optical instruments with those computed from chemical composition and thermodynamics. Results show that the model can represent the observed f（RH） and is appropriate for use as a component in other higher-order models.

Real-Time Mesoscale Forecast Support During the CLAMS Field Campaign

This paper reports the use of a specialized, mesoscale, numerical weather prediction （NWP） system and a satellite imaging and prediction system that were set up to support the CLAMS （Chesapeake Lighthouse and Aircraft Measurements for Satellites） field campaign during the summer of 2001. The primary objective of CLAMS was to validate satellite-based retrievals of aerosol properties and vertical profiles of the radiative flux, temperature and water vapor. Six research aircraft were deployed to make detailed coincident measurements of the atmosphere and ocean surface with the research satellites that orbited overhead. The mesoscale weather modeling system runs in real-time to provide high spatial and temporal resolution for forecasts that are delivered via the World Wide Web along with a variety of satellite imagery and satellite location predictions. This system is a multi-purpose modeling system capable of both data analysis/assimilation and multi-scale NWP ranging from cloud-scale to larger than regional scale. This is a three-dimensional, non-hydrostatic compressible model in a terrain-following coordinate. The model employs advanced numerical techniques and contains detailed interactive physical processes. The utility of the forecasting system is illustrated throughout the discussion on the impact of the surface-wind forecast on BRDF （Bidirectional Reflectance Distribution Function） and the description of the cloud/moisture forecast versus the aircraft measurement.

Spatial Variability and Radiative Impact of Aerosol along the Brahmaputra River Valley in India: Results from a Campaign

The first ever land campaign to study the spatial variability of the aerosol characteristics along the Brahmaputra river valley (BRV) in Assam, North-Eastern India, was conducted during 2011. Measurements were made over 13 locations for Aerosol Optical Depth (AOD), scattering coefficient, particulate matter, black carbon (BC) concentration and meteorological parameters. The BRV is divided into three sectors longitudinally viz western sector (WS), central sector (CS), and eastern sector (ES). Significant Spatial heterogeneity in AOD and BC concentration was observed (p < 0.05) with the highest values over WS and a continual decrease from WS to ES with aerosol dominance in PM2.5 category along the entire valley. The Angstrom coefficient measured using different wavelength pairs showed spatial variability indicating dominance of fine particles over WS and coarse particles in ES with a probable bimodal distribution. The scattering and absorption coefficient shows dominance of both types of aerosol over WS than other areas. The shortwave radiative forcing was higher over the WS than CS and ES of the valley. The campaign revealed that under favorable wind conditions, the BRV is loaded with significant amount of natural and anthropogenic aerosol during local winter and is influenced by the long-range transport of aerosols from the Indo-Gangetic plain.

Reflecting on Peter and the Wolf: Fantasy or Prophecy

The article discusses the socio-cultural aspect of the popular musical tale Peter and the Wolf by Sergei Prokofiev (1891-1953). The discussion takes into account the circumstances of composer’s life at time of writing the piece, as well as the political and ideological context of Soviet Russia of the 1930s. The main discussion is connected with the campaign of the Soviet authorities against formalism in musical art, which led to a ban on the staging of many works for the musical theater, including Prokofiev’s Romeo and Juliet commissioned by the Kirov (Mariinsky) Theater in Leningrad just a year before the ban. The circumstances surrounding the arrest of Prokofiev’s first wife are part of the discussion, along with an explanation of what “pioneer Peter” means. The author claims that, conceived as a children’s fairy tale, the work has an ambiguous ending, which can be viewed as a kind of prophecy expressed in Aesopian language.

A New Mathematical Modeling of the COVID-19 Pandemic Including the Vaccination Campaign

In a short time, many illustrative studies have been conducted on the mathematical modeling and analysis of COVID-19. There are not enough studies taking into account the vaccine campaign among these studies. In this context, a mathematical model is developed to reveal the effects of vaccine treatment, which has been performed recently, on COVID-19 in this study. In the proposed model, as well as the vaccinated individuals, a five-dimensional compartment system including the susceptible, infected, exposed and recovered population is constructed. Moreover, besides the positivity, existence and uniqueness of the solution, biologically feasible region are provided. The basic reproduction number known as expected secondary infection which means that expected infection among the susceptible populations caused by this infection is evaluated. In the numerical simulations, the parameter values taken from the literature and estimated are used to perform the solutions of the proposed model. Fourth-order Runge-Kutta numerical scheme is applied to obtain the results.

Introduction: Intestinal parasitism has been a challenge to overcome for the Mexican deworming campaign and this study determined the prevalence of these infections in schoolchildren treated with albendazole in Northwestern Mexico. Methods: Study sites in marginal conditions, with gastrointestinal infections and albendazole intervention were selected. The Faust and Kato Katz techniques were used to identify the parasites spp. and the NCSS software was used for statistical analysis. Results: A total of 450, 389 and 364 schoolchildren participated in 2005, 2006, and 2007 respectively during this study. The mean age was 7.9 (±1.3). The estimated prevalences were of 42%, 30% and 37% for protozoa infections, and 11%, 12% and 11% for helminth infections in 2005, 2006 and 2007 respectively. Conclusion: The education strategies should be integrated into the Mexican deworming campaign.

Public Health Campaigns and Medicine Use Awareness: A Systematic Literature Review

This study investigates the medicine awareness, which can be defined as the increase in knowledge and understanding of the general public on appropriate medicine use. Objective: To identify the characteristics of Public Health campaigns that focus on medicine use and/or medicine awareness. Study Design: Systematic review focusing on pre- and post-campaign surveys. Methods: Electronic databases: PubMed, Science Direct, Web of Knowledge, Scopus, Global Health, and Google Scholar were searched. Articles within the last 10 years, with a focus on adults over the age of 18 were used to report findings. Results: A total of 4336 studies were reviewed after which eight were identified, which focused on medicines use and/or awareness. Most campaigns emphasized the knowledge and understanding of patients on the importance of appropriate medicine use and drew a comparison from pre- to post-campaign results. A limited number of Public Health campaigns demonstrated an increase in the level of medicines use awareness of patients. Various tools were used to portray the message across in the campaigns. These included, video, written information, face to face approaches, as well as educational games. Four studies demonstrated a statistically significant increase, in awareness of the public in regards to medication. However, the remaining studies were not successful in portraying a significant impact. Conclusion: Most campaigns demonstrated a limited increase in level of medicine use awareness in their post-campaign surveys. The results support the need for a comprehensive Public Health campaign that focuses on medicine use.

Evaluation of the Effectiveness of the 2019 School-Based Awareness Campaign on Road Driving in the Municipalities of Cotonou and Abomey-Calavi in Benin

Being the leading death cause among young people in the world, road accidents are avoidable through the adoption of simple attitudes and behaviors. Handicap International Non-Governmental Organization (NGO) has launched an awareness campaign in secondary schools in the municipalities of Cotonou and Abomey-Calavito bring young Beninese users to adopt good attitudes and safe behavior while driving on the road. This study aims at assessing the effectiveness of this awareness campaign. It was an evaluative cross-sectional here-elsewhere type study, held in fourteen high schools in the cities of Cotonou and Abomey-Calavi, of which seven benefited from the campaign and seven did not. In each school, students were selected on the basis of two-stage random sampling. 656 students, 309 of whom were sensitized and 347 of whom were not, were included in this study. The campaign was quite effective. Students, teachers, and school officials’ perceptions of the campaign were positive. In addition, the sensitized students had a better level of knowledge (p = 0.001) and reported safer behaviors (p = 0.003) while driving on the road than those who were not aware. Although the effects are positive, they are still very small. Efforts must be continued and much remains to be done.

Data for this study were collected through the distribution of 247 well-structured questionnaires. Likert Scale was adopted for the analysis of the respondents. The results revealed that awareness is critically low. Though the respondents have concern for their environment in various degrees, majority dispose their e-waste alongside municipal wastes without knowing the implications. Awareness strategy was designed for sensitization campaign.

Monitoring of Ultrafine Particles in the Surrounding Urban Area of In-Land Passenger Ferries

Maritime transportation, widely used both in international transport of goods and touristic purposes, has been identified as a significant source of ultrafine particles (UFP). In-land passenger ferry is a source of UFP far less addressed;however, in locations with relatively high frequency of this transportation mode, it is expected that they contribute to an increase of their concentration. Moreover, the negative effects of UFP on human health and environment are known and therefore, monitoring UFP produced by ferries is vital to assess the degree of exposure of who work or live close to ferries’ terminals or downwind to their cruising path. This work aims to study the influence of in-land ferries activities on UFP in the urban/suburban areas near ferries’ terminals and downwind across the cruising path. The UFP monitoring campaign was carried out from September to December 2018 for 19 non-consecutive periods. The sampling sites were chosen in order to maximize measurements under downwind conditions and allow the association between ferry operation and UFP concentration response. Based on data collected, correlation analysis was performed between ferry’s traffic and particle number counting (PNC) of UFP, and also with meteorological variables. Results show an increase in PNC ranging from 25 to 197% during the third minute around a ferry movement and are moderate to positive significant correlations between PNC values and the number of ferry operations (r = 0.79 to r = 0.94), showing that UFP emitted by in-land ferries contributes to PNC increase. Moreover, negative correlations (r = -0.85 to r = -0.93) between PNC and wind intensity were also found.
