UTCI as the NWP model ALADIN (CHMI) output – first experiences

The article includes a summary of basic information about the Universal Thermal Climate Index (UTCI) calculation by the numerical weather prediction (NWP) model ALADIN of the Czech Hydrometeorological Institute (CHMI). Examples of operational outputs for weather forecasters in the CHMI are shown in the first part of this work. The second part includes results of a comparison of computed UTCI values by ALADIN for selected place with UTCI values computed from real measured meteorological data from the same place.

The evaluation of biothermal conditions for various forms of climatic therapy based on UTCI adjusted for activity

The objective of this study was to assess biothermal conditions in the selected Polish health resorts for specific forms of climatic therapy. We calculated Universal Thermal Climate Index (UTCI) for ten-year period (2008- 2017) and then added adjustment terms, taking into account changes in metabolic rates during various physical activities from resting to vigorous exercise. The adjusted UTCI values increased with rising activity, implying that warmer parts of the year were unsuitable for intensive forms of climatotherapy. These results demonstrate that the UTCI adjustment procedure provides well-balanced assessments of bioclimatic conditions for the purpose of climatic treatment considering the level of activity

The impact of COVID-19 on education in Poland: Challenges related to distance learning

The spread of COVID-19 all over the world triggered major changes in the organization of the education in many countries. Governments have adopted various solutions to reduce the disruption caused to education. This article, which is based on survey research (N=246) conducted among teachers in various types of schools in Poland, provides an analysis of the solutions in the field of distance learning and the organization of learning process during lockdown. The results show that teachers encountered a number of difficulties in distance learning. They concerned, among others: lack of access among certain students to computers, insufficient competences of teachers to teach remotely, work organization, and the fact that students were bored with this learning form. The advantages included, among others: increasing digital competences and developing new forms of assessing students’ knowledge.

Bioclimatic conditions and thermal seasons of the year in Szczecin

Climate change is an empirical fact evidenced by subsequent IPCC reports. The observed climate change is also manifested in the altered date of occurrence and duration of the seasons in a year. Variability of thermal conditions due to climate warming will have its toll on the bioclimatic conditions. The assessment of bioclimatic conditions was conducted with the use of Universal Thermal Climate Index (UTCI). The present elaboration is based on hourly values of the following meteorological elements: air temperature, relative air humidity, wind speed and cloud cover. The meteorological data were obtained from the Institute of Meteorology and Water Management – National Research Institute (IMGW-PIB) in Szczecin and cover the period 2000-2019. Variability of bioclimatic conditions is considered per periods corresponding to thermal seasons of the year as identified by the Gumiński (1948) method on the basis of monthly air temperature values. The analysed UTCI values with respect to thermal seasons indicate that mean UTCI values in the period 2000-2019 representative for thermal summer amount to 22.6°C, thermal spring 9,9°C, thermal autumn 8.4°C, thermal winter -10.4°C, early spring -4.6°C, and early winter -7.9°C. For the periods with identified lack of thermal winter, mean UTCI value was -6.6°C. The aim of the present paper is an attempt to assess the variability of biothermal conditions as calculated using the UTCI index against the thermal seasons of the year in Szczecin.

Stages of spatial dispersion of the COVID-19 epidemic in Poland in the first six months (4 March-20 September, 2020).

The article is a continuation of research published by the author elsewhere (Śleszyński, 2020). The elaboration presents the regularity of spatial distribution of infections during the first six months after the detection of SARS-CoV-2 coronovirus in Poland under strong lockdown conditions. The main aim is to try to determine the basic temporal-spatial patterns and to answer the questions: to what extent the phenomenon was ordered and to what extent it was chaotic, whether there are any particular features of spread, whether the infection is concentrated or dispersed and whether the spreading factors in Poland are similar to those observed in other countries. Day by day data were used according to the counties collected in Rogalski’s team (2020). The data were aggregated to weekly periods (7 days) and then the regularity of spatial distribution was searched for using the cartogram method, time series shifts, rope correlation between the intensity of infections in different periods, Herfindahl-Hirschman concentration index (HHI) and cluster analysis. A spatial typology of infection development in the population was also performed. Among other things, it was shown that during the first period (about 100 days after the first case), the infections became more and more spatially concentrated and then dispersed. Differences were also shown in relation to the spread of the infection compared to observations from other countries, i.e. no relation to population density and level of urbanization.

Travel preferences of Finnish cross-border tourists: Opportunities and limitations for Russian Karelia

The study aims to examine travel preferences of Finnish cross-border tourists with special reference to the Republic of Karelia, Russia. Data were collected using paper-based and online surveys from 300 respondents travelling from Finland to the Russian Karelia. Although cross-border tourists are a significant part in the inbound tourist flow to Russian Karelia, several obstacles for this type of tourism have been revealed. Measures to stimulate Finnish tourists to travel to Russian Karelia are suggested. The results of this study can be used to improve Karelian tourist products by providing services as expected by tourists. The findings are limited to visitors of Russian Karelia and should therefore be interpreted with caution.

The Chinese minority in Bucharest: A case study of Chinese children raised and cared for by Romanian nannies

Since 1990, many Chinese immigrants have come to Romania. These Chinese persons are full time involved in the profitable wholesale and retail trade activities; they have families and children, cared for by Romanian nannies. The study is focused on the particularities of an intercultural dialogue, unique and recenlty highlighted in the Romanian society: between the Romanian nannies and Chinese children, located in a representative urban area for the Chinese minority. The aim of paper is to analyses how two cultures have interacted for the purpose of child care, focusing on the ways in which the life, experiences, attitudes and opportunities of Chinese children are socially and spatially shaped, influenced and structured by cultural features of the Romanian nannies.

Spatio-temporal analysis of the development of the COVID-19 epidemic (pandemic) in Poland: First phase of development

The purpose of this study is to present a description of the course of the COVID-19 epidemic in Poland in the space-time dimension in the period from March 15th to August 8th 2020. The result of the conducted research is a presentation of the regional differentiation of the course of the epidemic in Poland, the comparison of the intensity of SARS-CoV-2 infections in particular voivodeships, the determination of the degree of similarity in the course of the pandemic development process in individual regions (voivodeships) of the country, and also the indication of the factors which could be taken into account when attempting to explain the interregional differences in the course of the epidemic. The conducted research shows, among other things, that: (1) in terms of time, the development of the epidemic was generally monotonic, however the increase in new infections was rather cyclical, (2) in the spatial dimension, the development of the epidemic was rather random, although the greatest number of infections was characteristic of the most populated regions of the country, (3) the level of infections in Poland was mainly positively influenced by: population density, working in industry, people beyond retirement, age as well as a poorly developed material base of inpatient care.
