The Use of a Statistical Model of Storm Surge as a Bias Correction for Dynamical Surge Models and its Applicability along the U.S. East Coast

The present study extends the applicability of a statistical model for prediction of storm surge originally developed for The Battery, NY in two ways: I. the statistical model is used as a biascorrection for operationally produced dynamical surge forecasts, and II. the statistical model is applied to the region of the east coast of the U.S. susceptible to winter extratropical storms. The statistical prediction is based on a regression relation between the “storm maximum” storm surge and the storm composite significant wave height predicted ata nearby location. The use of the statistical surge prediction as an alternative bias correction for the National Oceanic and Atmospheric Administration (NOAA) operational storm surge forecasts is shownhere to be statistically equivalent to the existing bias correctiontechnique and potentially applicable for much longer forecast lead times as well as for storm surge climate prediction. Applying the statistical model to locations along the east coast shows that the regression relation can be “trained” with data from tide gauge measurements and near-shore buoys along the coast from North Carolina to Maine, and that it provides accurate estimates of storm surge

The Use of MERRA-2 Near Surface Meteorology to Understand the Behavior of Planetary Boundary Layer Heights Derived from Wind Profiler Data over the US Great Plains

The atmospheric general circulation model (GCM) that underlies the MERRA-2 reanalysis includes a suite of physical parameterizations that describe the processes that occur in the planetary boundary layer (PBL). The data assimilation system assures that the atmospheric state variables used as input to these parameterizations are constrained to the best fit to all of the available observations. Many studies, however, have shown that the GCM-based estimates of MERRA-2 PBL heights are biased high, and so are not reliable for boundary layer studies.A 20-year record of PBL heights was derived from Wind Profiler (WP) backscatter data measured at a wide network of stations throughout the US Great Plains and has been validated against independent estimates. The behavior of these PBL heights shows geographical and temporal variations that are difficult to attribute to particular physical processes without additional information that are not part of the observational record.In the present study, we use information on physical processes from MERRA-2 to understand the behavior of the WP derived PBL heights. The behavior of the annual cycle of both MERRA-2 and WP PBL heights shows four classes of behavior: (i) canonical, characterized by a monthly progression in PBL height that follows the solar insolation, (ii) double peak, characterized by canonical behavior that is interrupted by a minimum in July, (iii) late peak, characterized by a suppressed heights in May and June, and return to canonical in July and August, and (iv) early peak where the PBL height rises with solar insolation but is suppressed later in the summer. The explanation for these behaviors and the relationship to local precipitation, temperature, sensible and latent heat fluxes, net radiation and aerosol load is articulated using information from MERRA-2

Pengaruh Penggunaan Power Point Berbasis Animasi terhadap Hasil Belajar Siswa pada Materi Dimensi Tiga

This article discusses the use of PowerPoint animation in learning with the aim of knowing the differences in learning outcomes of students whose learning uses power points and without using power points in three-dimensional topics. The method used is an experimental design with a True Experimental Design, namely Posttest-Only Design. The sampling technique used cluster random sampling. Student learning outcomes data were obtained through the learning outcome test instrument in the form of essays. Data analysis using descriptive analysis techniques and inferential data analysis. Hypothesis testing using a parametric analysis t-test. The results of the analysis show that the average learning outcomes of students who are taught using power points are higher than those of students taught conventionally. One of the factors that support the improvement of student learning outcomes is a learning approach to geometric shapes that involves interesting visualization. Interesting visualization makes students not just imagine something abstract but can directly observe the object being studied

Stability, elites and development policy in the new order Indonesia 1966-1983

One of the most striking characteristics of Third World countries is political instability. Although not all Third World states are politically unstable, witness for example Saudi Arabia and Nepal, many nations of both democratic and authoritarian leanings have experienced strong political challenges in maintaining established political order and national unity. These political challenges can take the forms of mass demonstration, riots or even coups

The Use of MERRA-2 Near Surface Meteorology to Understand the Behavior of Planetary Boundary Layer Heights Derived from Wind Profiler Data over the US Great Plains

The atmospheric general circulation model (GCM) that underlies the MERRA-2 reanalysis includes a suite of physical parameterizations that describe the processes that occur in the planetary boundary layer (PBL). The data assimilation system assures that the atmospheric state variables used as input to these parameterizations are constrained to the best fit to all of the available observations. Many studies, however, have shown that the GCM-based estimates of MERRA-2 PBL heights are biased high, and so are not reliable for application related to constituent transport or the carbon cycle. A new 20-year record of PBL heights was derived from Wind Profiler (WP) backscatter data measured at a wide network of stations throughout the US Great Plains and has been validated against independent estimates. The behavior of these PBL heights shows geographical and temporal variations that are difficult to attribute to particular physical processes without additional information that are not part of the observational record. In the present study, we use information on physical processes from MERRA-2 to understand the behavior of the WP derived PBL heights. The behavior of the annual cycle of both MERRA-2 and WP PBL heights shows three classes of behavior: (i) canonical, where the annual cycle follows the annual cycle of the sun, (ii) delayed, where the PBL height reaches its annual maximum after the annual maximum of the solar insolation, and (iii) double maxima, where the PBL height begins to rise with the solar insolation but falls sometimes during the summer and then rises again. Although the magnitude of these types of variations is described by the WP PBL record, the explanation for these behaviors and the relationship to local precipitation, temperature, hydrology and sensible and latent heat fluxes is articulated using information from MERRA-2

Faktor yang Berhubungan dengan Kelelahan Kerja pada Karyawan Bagian Penggorengan di Pabrik Abon Vivi Kefamenanu Kabupaten Timor Tengah Utara

Meat floss production requires time as it involves a heavy workload. In addition, poor posture and work environment may cause fatigue and workplace accidents for the workers. There are two causes of fatigue, physical fatigue which is due to work-related environment factors and non-physical fatigue which is due to individual factors. Fatigue can affect health and work performance leading to productivity loss and accidents. This research aims to determine factors associated with work fatigue of workers at the Vivi Meat Floss Factory in Kefamenanu. This research was analytic with a cross-sectional design. The population in this study consisted of all workers (32 women) at the factory. A total sampling technique was applied to select the sample. The data were analyzed using logistic regression. The results showed that the factors related to work fatigue were job tenure period (p-value of 0.001 < 0.05), age (p-value of 0.002 < 0.05), work posture (p-value of 0.002 < 0.05), duration (p-value of 0.006 < 0.05), and temperature (p-value of 0.002 < 0.05)

Analisis Peran Supervisi Akademik Kepala Sekolah Kepada Guru IPA DI SMP Negeri 20 Kupang

One important element in the implementation of education is the principal, who has the task of supervising and fostering the pattern of ongoing teaching activities, for example supervising all teachers in schools to help improve the quality of learning and the performance of a teacher. Often teachers experience various obstacles, which can arise from various factors so that the learning process is less than optimal. Therefore, the principal needs to provide academic supervision to help develop teacher competence and professionalism. The purpose of this study was to determine how the principal's academic supervision of science teachers at SMP Negeri 20 Kupang and the constraints in implementing academic supervision. The approach used is qualitative. Data collection techniques are observation, interviews, documentation, and questionnaires. The data were analyzed using the stages of data reduction, data presentation, and conclusion drawing. The results showed that the implementation of the principal's academic supervision of the teacher had been carried out well, the principal had planned by preparing the supervision instrument and informing the schedule of supervision, the implementation of supervision using various techniques and principles. Evaluation and follow-up of academic supervision are carried out by discussing the results of supervision with the teacher, the school also holding workshops/training to improve and improve the quality of teachers in carrying out their duties at school. the implementation of academic supervision experiences obstacles that arise from the teacher, namely the lack of preparation of learning devices, the teacher does not master the material during the learning process and the teacher does not master the class, where it seems that students are difficult to control in the learning process
