This trend causes transformation in the geosphere, biosphere, pedosphere, atmosphere and hydrosphere, affecting the human‐environment sys‐ tem over both short‐ and long‐term timescales. Cities represent a complex and highly dynamic interface be‐ tween Earth components (atmosphere, land, water, etc.) and societal factors (health, social equity, life quality, economy, etc.). At the same time, cities are very sensitive to climate change. This vulnerability is strongly pro‐ nounced in the North, especially in the Arctic, a region that is warming at twice the rate as the global average, and has direct and indirect impacts on the local livelihoods, infrastructure, water resources, ecology and air quality. The World Meteorological Organization (WMO) within the UN Sustainable Development Goals (SDGs) and New Urban Agenda is promoting safe, healthy and resilient cities through the development of science‐based Integrated Urban Weather, Environment and Climate Systems and Services (IUS) for sustainable cities under changing climate. The WMO suggested novel concept and methodology for the Urban Integrated Hydro‐ Meteorological, Climate and Environmental Services (Baklanov et al., 2018; WMO, 2019; Grimmond et al., 2020) to support safe, healthy, sustainable and resilient cities are actively realized for a number of cities around the world. The Guidance on IUS, Volume II: Demonstration Cities (WMO, 2020) uses information gath‐ ered from more than 30 demonstration cities to provide examples of the types of IUS and their placement within distinct administrative frameworks. However, among these more than 30 cities, already successfully realizing such approach for sustainable urban development, only a few of winter cities considered (Baklanov et al., 2020) and no Arctic cities involved and analyzed yet. However, northern cities have a strong specific and not always recipes, recommended for other climatic zones, are suitable for them. Previous studies of urban sensitivity to climate change have mostly focused on lower and mid‐latitude cit‐ ies and rarely considered analysis of Northern/Arctic cities. Due to the specific climatic conditions and societal organization Northern cities embrace many challenges in the advancement of knowledge about physical, chemical, ecological, socio‐economic and environmental change, their relationships and implications for the human‐environment system. Some of the important issues that require in‐depth studies include the effects of urban meteorology such as heat islands and the interactions of stably stratified boundary layers with urban

PLenary session 13 elevated air pollution episodes in a changing climate. In addition, as urbanization progresses and lifestyles global‐ ize, the need for agricultural and industrial products increases. This poses environmental challenges in both cas‐ es, local production (unique ecosystems) and transportation to the Arctic (infrastructure development). Moreo‐ ver, due to the cold weather conditions, high‐energy consumption is typical of northern cities. With limited po‐ tential for renewable energy generation, adopting sustainable life styles is of particular challenge. In the Arctic, particularly considering the present status, indigenous communities and population level, the urbanization process involves a large spectrum of settlements of various sizes. In order to understand the social‐environmental effects of urbanization under rapid climate change a multiscale approach is necessary in order to be beneficial to the whole Arctic society. This presentation provides an overview of the current efforts towards future northern IUSs on Arctic ur‐ banization under climate change undertaken by the international initiative Air Pollution in the Arctic: Climate, Environment and Society (PACES) (Arnold et al., 2016; Schmale et al., 2018), the Pan‐Eurasian Experiment (PEEX) programme (Kulmala et al., 2015; Lappalainen et al., 2021), the WMO Global Atmospheric Watch Urban Research Meteorology and Environment (GURME) project (WMO, 2019; Sokhi et al, 2021), as well as several ongoing and previous bilateral and international projects, e.g.: FP6 EnviroRISKS (Baklanov and Gordov, 2006; Baklanov et al, 2013); UHIARC (Konstantinov et al, 2018; Varentsov et al, 2018); Belmont Forum's HIARC (Miles and Esau, 2017, 2020) and SERUS (Esau et al., 2020), NordForsk TRAKT‐2018 (Mahura et al., 2018; Esau et al., 2021), Kola Arctic studies etc. (Baklanov et al., 2012; Amosov et al., 2014, 2020; Penenko et al., 2015) and Horizon‐2020 iCUPE (Petäjä et al. 2020). The recently organized 4th PACES Open Science meeting (26‐28 May 2021) on its Session 2: “Integrated Urban Systems (IUS): Twin cities –GURME initiative” concluded that: ‐ Complex multidisciplinary approach is needed for building climate and environmentally smart and sus‐ tainable Arctic cities; ‐ Improvements and adaptation of the novel WMO concept of the IUS for Arctic and winter cities are im‐ portant and require further research; ‐ It is decided to propose a new GURME project on IUS for Northern Twin Cities. Cities in focus and some initial pairs of twin cities have been identified (e.g., Rovaniemi‐Apatity; Tromso‐Murmansk/Salekhard; Fair‐ banks‐Norilsk/Nadym). ‐ Key science focus will be on very stable boundary layers of winter and Arctic cities and their interactions with urban processes, air pollution and climate change.

In this report, numerical methods of linear algebra and the least‐squares collocation method in combination with modern algo‐ rithms of an iterative process acceleration are applied to modelling and simulation of composite beams bending [1]. The quasi‐static loading process with repeated solution of systems of nonlinear algebraic equations and boundary value problems for ordinary differential equations is considered to analyze beams SSS [1, 2].
