Underlying Processes

Abstract The subtropical part of the eastern Australian seaboard experiences intense cyclonic activity. The severe damage caused by the intense storms in the region, known as east coast lows (ECLs), has motivated a number of recent studies. Cyclones in this region appear to be driven by a combination of different (barotropic and baroclinic) formation mechanisms, consistent with the view emerging in the last decades that cyclones span a continuous spectrum of dynamical structures, with the barotropically driven tropical cyclone and the baroclinically driven extratropical cyclone being only the extremes of such a spectrum. In this work we revisit the climatology of cyclone occurrence in the subtropical east coast of Australia as seen in a global reanalysis, systematically applying classification criteria based on the cyclone vertical structure and thermal core. Moreover, we investigate the underlying processes driving the cyclone rapid intensification by means of an atmospheric limited-area energetics analysis. We show that ECLs have different spatial patterns according to the cyclone thermal structure, with the fraction of hybrid cyclones being larger toward the tropics and closer to the coast. Moreover, we find that explosively deepening cyclones in this region are driven by a different combination of processes with respect to the global case, with barotropic processes in the surrounding environment having a more dominant role in the energetics of cyclone rapid intensification. The findings of this work contribute to understanding the physical processes underlying the formation and intensification of Australian east coast lows and the associated coastal damage and risk.

The spreading of oil in an open ocean may cause serious damage to a marine environmental system. Thus, an accurate prediction of oil spill is very important to minimize coastal damage due to unexpected oil spill accident. The movement of oil may be represented with a numerical model that solves an advection-diffusion-reaction equation with a proper numerical scheme. In this study, the spilled oil dispersion model has been established in consideration of tide and tidal currents simultaneously. The velocity components in the advection-diffusion-reaction equation are obtained from the shallow-water equations. The accuracy of the model is verified by applying it to a simple but significant problem. The results produced by the model agree with corresponding analytical solutions and field-observed data. The model is then applied to predict the spreading of an oil spill in a real coastal environment.

Coastal Damage

The coastal areas of both Jayapura Municipality and Regency which is directly opposite to the Pacific Ocean with the multifunctional use is a vulnerable area to disasters. The coastal vulnerability is determined by considering some influential factors, that is geomorphology and elevation to minimize the coastal damage impacts. The purpose of this study is to determine the coastal vulnerability index of Jayapura City and Regency focusing on the coastal geomorphology and elevation. The study area covers a coastal area of 241.86 km along the coastlines of Jayapura Municipality and Regency. The study method includes data collection on the coastal geomorphology and elevation characteristics. The value of coastal vulnerability index of each parameter is determined by dividing into five categories of coastal vulnerability. The result shows territorial division as follows: 145.88 km (61.18%) was not vulnerable, 33.14 km (13.90%) was less vulnerable, 29.03 km (12.17%) was a moderate vulnerability, 12.12 km (5.08%) was vulnerable, and the remaining 18.29 km (7.67%) was very vulnerable. The coastal vulnerability of Jayapura City coastal areas categorized into three classes, i.e. not vulnerable, moderate vulnerable and vulnerable, while the Jayapura Regency coastal areas felt into the following classes: not vulnerable and moderate vulnerable. The most vulnerable areas were of Abepura District, South Jayapura District and Muaratami District, all in the Jayapura Municipality administration. Those areas with high elevation level were not vulnerable at all.

Penelitian ini bertujuan untuk mengidentifikasi kerusakan pesisir akibat konversi lahan bakau menjadi tambak yang kaitannya dengan perubahan garis pantai di Kabupaten Cirebon. Metode observasi dengan analisis deskriptif kualitatif terhadap faktor penurunan luasan ekosistem bakau dan sedimentasi. Data-data yang dikumpulkan yaitu energi fluks gelombang, peta karakteristik pantai dan peta sebaran bakau. Hasil dari pembobotan menunjukkan desa pantai yang termasuk kategori amat sangat diutamakan (A) adalah Gebang Kulon dan Gebang Ilir. Selanjutnya, pantai yang memiliki kategori sangat diutamakan tersebar merata hampir disetiap desa, kecuali desa Bendungan, Mundu dan Kalipasung yang kategori diutamakan (B), dan desa Tawang sari kategori kurang diutamakan (D). Kata Kunci: Identifikasi pesisir, ekosistem hutan bakau, kategori, Cirebon The study is to identify the coastal damage due to the conversion of coastal mangrove to fish ponds that is correlated with coastal changes in Cirebon regency. By using methods observation with qualitative descriptive analysis to the factor decrease the extend of mangrove ecosytems and sedimentation. Data collected are energy flux, coastal characteristic maps, and mangrove distribution map. Results of weighting indicates that coastal villages within avery high priority (A) is Gebang Kulon and Gebang Ilir. Furthermore, the beach has a high priority is spread evenly in almost every villages except Dam, Mundu, and Kalipasung villages those are in priority category (B), as well as the village of Tawang sari within a less priority category (D).

Mangrove Planting

Along the coast Keluruhan Pelintung has been an abrasion of 1.33-16.84 metres/year. This activity aims to increase the capacity of community awareness of coastal damage mitigation through counseling on abrasion prevention and green belt implementation techniques. The methods used were lectures, discussions, and classroom and field practice, followed by 28 community representatives. The results of the activity showed a significant increase in community's understanding of simple methods to prevent coastal damage which had a positive impact on ecology (coastal resilience) and the economy (alternative income). The method of planting mangroves on abrasive beaches is due to the influence of currents and waves and processing of mangrove fruit to produce syrup, diamonds and mangrove dodol (mangrove). The results of the economic analysis show that the pedada syrup (1 bottle @ Rp. 25,000) generates a profit of Rp. 3,192,000/month, wajik pedada (1 pack Rp. 10,000) Rp. 1,476,000/month, and dodol pedada (1 pack of Rp. 15,000) Rp. 2,760,000/month. The majority of the community stated that they supported and enthusiastically held this activity, namely 49.7% (Strongly Agree), 37.8% (Agree), 11.80% (Neutral) could accept and practice increasing community awareness of mitigating coastal damage by making mangrove planting efforts and diversification of processed mangrove products.

Coastal Damage

We examine the role of zonal Ekman transport along the coast of Senegal on 30 August, 2015 when the tropical disturbance associated with Tropical Cyclone Fred was located to the west of Senegal causing considerable coastal damage to coastal areas south of Dakar, Senegal. Ten-meter winds from three Weather Research and Forecast model simulations were used to estimate zonal Ekman transport, with the largest values found during the 30 August. The simulations are in agreement with limited coastal observations showing increasing southerly wind speeds during 30 August but are overestimated relative to the 3 coastal stations. The strong meridional winds translate into increased zonal Ekman transport to the coast of Senegal on 30 August. The use of a coupled ocean model will improve the estimates of Ekman transport along the Guinea-Senegalese coast. The observed damage suggests that artificial and natural barriers (mangroves) should be strengthened to protect coastal communities in Senegal.
