This was done through linear regression analysis which involves quantifying the relationship between one independent variable (explanatory, predictor) and one dependent variable (response). Thus, in our study, the dependent variable is represented by the LST product obtained through MODIS sensors in the period 2014-2018, while the independent variable is represented by IMD. The coefficient of determination (R2) obtained, higher than 0.5 for most of the year, indicates a statistically significant relationship between LST and IMD. The highest values of R2 are identified during the day spring and summer seasons. Thus, 70% and respectively 80% of the spatial variation of LST is explained by the distribution of IMD during these two seasons and the regression coefficients indicate, on the one hand, that the relationship between the two variables is a direct one (LST values increase at the same time with IMD values), and on the other hand, that the increase of LST corresponds to a gradient between 0.3-0.6 oC per 10% IMD. During the day, the lowest values of R2 appear in autumn and winter seasons, as a result of the local topography that facilitates the frequency of thermal inversions in this period of the year. On the other hand, during the night, R2 has values between 0.40 and 0.60, with the lowest values in the autumn season and the highest in the spring season, respectively.","PeriodicalId":306682,"journal":{"name":"Air and Water Components of the Environment Conference","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134070397","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is a great interest in creating a healthy and comfortable environment for the growing number of urban dwellers to live in, therefore different methods of combating and diminishing the urban heat island are being studied. One such method is to reduce the energy contribution of buildings to the formation of the urban heat island. In this paper we analyzed the effect of building envelopment, both by seasonal monitoring of surface temperatures using the thermal camera at different time intervals, and by numerical simulations of air temperature at different levels in the atmosphere, using ENVI-met, a three-dimensional non-hydrostatic microclimatic model. The data sets resulting from the monitoring of the surface temperature with the thermal camera showed that the temperature recorded at the surface is lower for the enveloped buildings than for the non-enveloped buildings, during the night but also during the day, less at noon. The numerical simulations were based on two scenarios: i) buildings with non-enveloped walls and ii) the same buildings but with enveloped walls, after running the scenarios for enveloped and non-enveloped buildings. The results showed that following the enveloping process the air temperature in the areas between the buildings is lower for the enveloped buildings, at different heights, both during the night and during the day.","PeriodicalId":306682,"journal":{"name":"Air and Water Components of the Environment Conference","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122927749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Soon, a number of water development plans were made for the catchment area of one of the tributaries, the River Túr/Tur. Plans outlining several technical alternatives have been prepared for the purpose of flood drainage, inland water drainage and water utilization. The implementation of the plans took place over decades, with construction started in 1914 interrupted due to the outbreak of World War I (Túr-Tisza branch channel). Most of the water facilities in the lower Hungarian section of the Túr River were built between 1926 and 1930 according to revised plans. The flood defense embankments on the Romanian river section were built in 1956-1957 and were further developed after the catastrophic floods of 1970, with half a dozen pumping stations set up to transfer the inland waters to the receiving area. Between 1972 and 1974, the Călineşti-Oaş dam and water reservoir were built. In our paper we describe the technical plans developed by the River Engineering Office in Szatmárnémeti (Satu Mare) at the end of the 19th century and the beginning of the 20th century for the regulation of the Túr river. We present the findings of the technical review of the plan and the calculations made for the water supply of the reservoir. We describe the development of the hydrometric network necessary for the foundation of hydrological calculations. When writing the paper, we used the technical documentation in the Upper Tisza Region Water Historical Collection in Nyíregyháza, which has not been published so far.","PeriodicalId":306682,"journal":{"name":"Air and Water Components of the Environment Conference","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133517111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Giurgiu","doi":"10.24193/awc2022_03","DOIUrl":"https://doi.org/10.24193/awc2022_03","url":null,"abstract":"Heatwaves are recognized, although there is still no general acknowledged definition, as periods of unusually hot and dry or hot and humid weather, which occur gradually and cease in the same way, lasting at least 2 to 3 days with visible impact on human activities. Episodes characterized by heatwaves induce excessively hot weather compared to the local climatic specific features. The period with or without heatwaves is different from a region to another, depending on the particularities of each area. This climatological hazard can be described as an advection of tropical air mass which, compared to the climatological standards, leads to reaching large positive temperature deviations, that in some cases will set new thermal records. In the northern hemisphere, in the area of temperate latitudes, which includes Romania, the highest values of air temperature are generally recorded from mid-June to the end of August. Heatwaves in Romania are mainly generated by the advection of continental hot air masses from North Africa, leading to a stable stratification of the atmosphere from ground levels to more higher ones. The ridge of the North African anticyclone extends either over Central Europe or Central Eastern Europe, up to Romania, generating heatwaves for the first scenario in the western regions of our country, whereas or the second one outside the Carpathians, most frequently in the Romanian Plain. In Romania, the most frequent heatwaves, taken by duration in time are those between 2 and 5 days. while analysed in terms of intensity, stand out those during summer months (June to August).","PeriodicalId":306682,"journal":{"name":"Air and Water Components of the Environment Conference","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130319916","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
