Student training with the METEO+TRANS model

Marwan Al-Kloub – Ph.D. student at the University of Jordan (School of Science, Department of Physics, Amman, Jordan) – attended extensive research training during two periods November 5 – December 9, 2018 and April 8 – May 5 May, 2019 at the University of Helsinki (Institute for Atmospheric and Earth System Research (INAR), Helsinki, Finland). The training included METEO+TRANS model package setup, testing, and running for localized geographical region in Jordan with focus on hypothetical accident scenarios at a planned nuclear power plant. The modelling system includes simulation of 3D meteorological and atmospheric pollution (with focus on radionuclides) fields and calculation of impact on population (through doses). The adaptation of models to accommodate conditions of the selected local domain (85×85 km2) in the north-eastern part of Jordan (Figure 1) was performed. The training also included a series of discussions on preparation of input data required for simulations, writing articles, making presentations, scientific publications overview, practicing approaches to independent vs. team-work vs. under supervision. Some of the simulation results are presented in Figure 2, which illustrates the horizontal wind field in selected layers above the terrain.

Figure 1: (a) Jordan map showing elevation above sea level (asl) and the chosen model domain (marked as 85×85 km2 area). Domain is shown from three different prospectives: (b) land use, (c) detailized map of elevation asl, and (d) interpolated elevation map as 17×17 grid. The location of the hypothetical Jordanian nuclear power plant is marked by a red square in the middle of the domain.
Figure 2: Simulated wind fields after 180 minutes: (row 1) January, (row 2) July, and (row 3) overall annual average. Each row subplots show the simulation results for layer 8 (425–550 m), layer 10 (700–850 m), and layer 12 (1000–1150 m), respectively.

This training was supervised by Visiting Professor Tareq Hussein and Dr. Alexander Mahura. I would like express my gratitude and appreciation to the University of Jordan and the University of Helsinki colleagues whom were actively involved into organization and carrying out of the research training visits, inspiring meetings and fruitful discussions, and especially, to the University’s professors, researchers, students and colleagues.
