The temperature differences between the city and rural sites (\u0394T) were calculated with a 1-hour time step. Average values \u200b\u200bof \u0394T in hours for individual months were determined and the daily variability of the frequency of occurrence of \u0394T for selected temperature ranges in seasons was determined. The frequency of occurrence of maximum daily \u0394T \u200b\u200b(between noon of the current day and noon of the previous day) and its long-term course were examined. The dependence of UHI on wind speed and cloudiness was analyzed. The obtained results were compared with the previous study concerning the years 1997\u20131999. In the currently analyzed period much stronger thermal contrasts were observed between the center of \u0141\u00f3d\u017a and the peripheral areas in summer, with averages exceeding 2\u00b0C at night. In relation to the years 1997\u20131999, the frequency of \u0394T\u00a0&gt;\u00a03\u00b0C has more than doubled. In winter, the average values \u200b\u200bof \u0394T are slightly lower than in the previous period, while the number of cases of \u0394T\u00a0&lt;\u00a00\u00b0C has increased, with a slight increase in the probability of the appearance of \u0394T\u00a0&gt;\u00a03\u00b0C. The maximum value of \u0394T recorded in the current period is 7.9\u00b0C and is slightly lower than for the years 1997\u20131999 (8.7\u00b0C). Contrary to the end of the last century, the highest values \u200b\u200bof \u0394T are similar in all seasons, and the number of \u0394T\u00a0&gt;\u00a07\u00b0C is much higher. Although the presented research does not allow to identify the causes of the observed UHI trends, the most probable are changes in the climatic conditions in the region and changes in the structure and metabolism of the city.<br \/>\n<strong><br \/>\nKeywords<\/strong>: urban heat island, urban climate, Lodz, air temperature<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Miejska wyspa ciep\u0142a w \u0141odzi w latach 2015\u20132018 na tle wcze\u015bniejszych bada\u0144 Urban heat island in Lodz in 2015\u20132018 in relation to previous studies Ewelina Krawczyk, Krzysztof Fortuniak, Szymon Wilk Przegl\u0105d Geofizyczny (2022) vol. 67, iss. 1-2, pp. 3-18 https:\/\/doi.org\/10.32045\/PG-2022-028&hellip;<\/p>\n","protected":false},"author":3,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-1728","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/ptgeof.pl\/index.php?rest_route=\/wp\/v2\/pages\/1728","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ptgeof.pl\/index.php?rest_route=\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/ptgeof.pl\/index.php?rest_route=\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/ptgeof.pl\/index.php?rest_route=\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/ptgeof.pl\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=1728"}],"version-history":[{"count":9,"href":"https:\/\/ptgeof.pl\/index.php?rest_route=\/wp\/v2\/pages\/1728\/revisions"}],"predecessor-version":[{"id":1823,"href":"https:\/\/ptgeof.pl\/index.php?rest_route=\/wp\/v2\/pages\/1728\/revisions\/1823"}],"wp:attachment":[{"href":"https:\/\/ptgeof.pl\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=1728"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
