Air Movement

Designing configuration of buildings and streets in an urban area by maximizing air movement is an approach of the sustainable city. The existing buildings and streets of an urban area can affect the microclimate formed, including the airflow. The airflow can be used to create a comfortable city environment. Jalan Gajahmada is one of the economic strategic areas in Pontianak City which requires a comfortable condition to support activities there. The airflow that occurs in Gajahmada Street affects the conditions that occur now. This paper aims to provide an overview of airflow conditions on Gajahmada Street Area. The research method is through computer simulations using the Envi-Met simulation program. The data used local climate data and field data based on surveys. Through the analysis, it is known that the airflow is strongly influenced by the direction of the wind, the surface mass of the building and the ratio between the height of the building to the width of the streets that is formed from the distance between building masses (H / W).

AbstractWe reanalyzed mass balance records at Taku and Lemon Creek Glaciers to better understand the relative roles of hypsometry, local climate and dynamics as mass balance drivers. Over the 1946–2018 period, the cumulative mass balances diverged. Tidewater Taku Glacier advanced and gained mass at an average rate of +0.25 ± 0.28 m w.e. a–1, contrasting with retreat and mass loss of −0.60 ± 0.15 m w.e. a−1 at land-terminating Lemon Creek Glacier. The uniform influence of regional climate is demonstrated by strong correlations among annual mass balance and climate data. Regional warming trends forced similar statistically significant decreases in surface mass balance after 1989: −0.83 m w.e. a–1 at Taku Glacier and −0.81 m w.e. a–1 at Lemon Creek Glacier. Divergence in cumulative mass balance arises from differences in glacier hypsometry and local climate. Since 2013 negative mass balance and glacier-wide thinning prevailed at Taku Glacier. These changes initiated terminus retreat, which could increase dramatically if calving begins. The future mass balance trajectory of Taku Glacier hinges on dynamics, likely ending the historic dichotomy between these glaciers.

Binding Agreement

The BOT (Build Operate Transfer) Agreement between Bogor Municipal Government and PT Pancakarya Grahatama Indonesia is an agreement to optimize Baranangsiang terminal assets as stated in the agreement Number: 601 / Perj.418-BPKAD / 2012 / Number: 005 / PGI / DIR / VI / 2012 . Until now, the agreement of both parties has not been able to be considered because of the change of authority of the terminal which formerly the authority of the City Government of Bogor to switch to the Central Government, resulting problems Whether the Government / Mayor Bogor can cancel the unilateral agreement BOT in the construction of Terminal Baranangsiang viewed from the point Civil Code? The research method used is normative legal research method supported by interview and field data. Based on the analysis that the BOT agreement between Bogor City Government and PT Pancakarya Grahatama is a valid and binding agreement between both parties and can not be canceled unilaterally by Bogor City Government, although there are new regulations that change the authority of terminal A Baranangsiang become the authority of Central Government . The Agreement may be canceled if it violates Article 1320 of the Criminal Code or violates the subjective and objective terms of the validity of the agreement. When the agreement is mutually agreed upon by both parties, the agreement must continue and act as a binding law as regulated in Article 1338 of the Criminal Code. Bogor City Government should immediately provide certainty to the PT Pancakarya Grahatama Indonesia for Baranangsiang terminal revitalization project can be immediately realized and need a revision (adedendum) agreement between the Government of Bogor City with PT Pancakarya Grahatama Indonesia related to changes in authority of terminal A Baranangsiang between PT. PGI with the Central Government.

Topsis Model

New towns and cities are proposed as the places for absorbing the population overflow and limiting the population growth in metropolises. In Iran, these towns and cities are built very close to the metropolises, and gradually, they are being used only as dormitories. The new town of Pardisan is built 13 kilometers southwest of Qom as the largest new town of the urban district of Qom in order to organize the residence system and absorb the population overflow of the metropolis of Qom and reduce its problems. This paper studies the function of the Pardisan new town as the absorber of the population overflow of Qom and also the residents’ satisfaction with this town. The research method adopted by this study is based on the library, documentary, and field data, and also interviews and collection of data by questionnaires and TOPSIS model. The results of this research indicate that many of the families living in the Pardisan town constitute the population overflow of the metropolis of Qom; Among the most important reasons for the migration of families to the Pardisan town is the low cost of land and residence, and 4.67 percent of the residents do not like to live in this town. This unsuccess is mostly due to lack of job and activity in this town, and therefore, the residents are less satisfied with the town.

<p>The majority of studies are dedicated to the analysis of climate change and climate models with no regard for data visualization part. Therefore, this research is aimed at highlighting challenges, with an emphasis on spatial referencing that can occur while visualizing CORDEX data. CORDEX data are stored in NetCDF file format, and sometimes georeferencing may be misconceived in QGIS software. For this reason, two techniques of georeferencing data are examined in this work. The first way of data georeferencing is re-projecting coordinates from original projection to an interpolated latitude/longitude grid. The second way is re-encrypting initial data file so that QGIS is able to interpret projection information. Preference of using QGIS explained by two reasons: it is open source GIS application and it has expanded visualization toolkit.</p><p>In addition, there are a great deal of climate models based on CORDEX data for some regions whereas there is a lack of climate projections for particular areas. In this regard, carrying out analysis for the region of Kazakhstan is beneficial. Outcomes of this research may stimulate spreading local climate models for Kazakhstan territory. Results are represented in the form of maps of Kazakhstan illustrating temperature change over 21<sup>st</sup> century time period.</p>

Weather Pattern

Abstract. To understand past flood changes in the Rhine catchment and in particular the role of anthropogenic climate change in extreme flows, an attribution study relying on a proper GCM (general circulation model) downscaling is needed. A downscaling based on conditioning a stochastic weather generator on weather patterns is a promising approach. This approach assumes a strong link between weather patterns and local climate, and sufficient GCM skill in reproducing weather pattern climatology. These presuppositions are unprecedentedly evaluated here using 111 years of daily climate data from 490 stations in the Rhine basin and comprehensively testing the number of classification parameters and GCM weather pattern characteristics. A classification based on a combination of mean sea level pressure, temperature, and humidity from the ERA20C reanalysis of atmospheric fields over central Europe with 40 weather types was found to be the most appropriate for stratifying six local climate variables. The corresponding skill is quite diverse though, ranging from good for radiation to poor for precipitation. Especially for the latter it was apparent that pressure fields alone cannot sufficiently stratify local variability. To test the skill of the latest generation of GCMs from the CMIP5 ensemble in reproducing the frequency, seasonality, and persistence of the derived weather patterns, output from 15 GCMs is evaluated. Most GCMs are able to capture these characteristics well, but some models showed consistent deviations in all three evaluation criteria and should be excluded from further attribution analysis.

On time-scales of less than about 100 years, when the ice topography can be considered stationary, the extent of Antarctic blue-ice areas is governed mainly by the surface mass balance. In and near high-elevation blue-ice areas, ablation is due entirely to sublimation. An estimate of the mass-balance profile ranging from a blue-ice area to the adjacent snow surface is presented. By considering changes in sublimation induced by variations in local climate, the deviation from the mass-balance profile is evaluated. It is concluded that even for considerable changes in local climate these deviations remain relatively small and have only little effect on the extent of a blue-ice area. This can be attributed mainly to the steep mass-balance profile.

<p>Climate change will lead to increases in the flood risk in low-lying coastal areas. Understanding the magnitude and impact of such changes is vital to design adaptive strategies and create awareness. In  the  context  of  the  CoDEC  project  (Coastal  Dataset  for  Evaluation  of  Climate  impact),  we  developed a consistent European dataset of extreme sea levels, including climatic changes from 1979 to 2100. To simulate extreme sea levels, we apply the Global Tide and Surge Model v3.0 (GTSMv3.0), a 2D hydrodynamic model with global coverage. GTSM has a coastal resolution of 2.5 km globally and 1.25 km in Europe, and incorporates dynamic interactions between sea-level  rise,  tides  and  storm surges. Validation of the dataset shows a good performance with a mean bias of 0-.04 m for the 1 in 10-year water levels. When analyzing changes in extreme sea levels for the future climate scenarios, it is projected that by the end of the century the 1 in 10-year water levels are likely to increase up to 0.5 m. This change is largely driven by the increase in mean sea levels, although locally changes in storms surge and interaction with tides can amplify the impacts of sea-level rise with changes up to 0.2 m in the 1 in 10-year water level.</p><p>The CoDEC dataset will be made accessible through a web portal on Copernicus Climate Data Store (C3S). The dataset includes a set of Climate Impact Indicators (CII’s) and new tools designed to evaluate the impacts of climate change on different sectors and industries. This data service will support European coastal sectors to adapt to changes in sea levels associated with climate change. In this presentation we will also demonstrate how the C3S coastal service can be used to enhance the understanding of local climate impacts.</p>
