Characteristics of the urban heat island in the city of Salamanca, Spain
In this paper the urban heat island (UHI) of the city of Salamanca, Spain is examined. The temporal evolution of the intensity of the UHI for the three-year period between 1996 and 1998 was studied by comparing the temperatures in an urban area and those in a nearby rural area. The results pointed t...

R.Urban heat islandnegative UHImeasuring transectsSalamancaSpainURBAN HEAT ISLANDNEGATIVE UHIMEASURING TRANSECTSSALAMANCASPAINIn this paper the urban heat island (UHI) of the city of Salamanca, Spain is examined. The temporal evolution of the intensity of the UHI for the three-year period between 1996 and 1998 was studied by comparing the temperatures in an urban area and those in a nearby rural area. The results pointed to the existence of a nocturnal UHI, whose highest mean value was recorded in autumn (3.2 ºC). Using the transect selection method, the spatial distribution of the UHI was analyzed. The lowest nocturnal temperatures were observed in the outskirts of the city, mainly in green areas close to the river. The daytime mean temperatures revealed a negative UHI, the lowest temperatures were recorded in the urban area, where the buildings, which afford shade, prevent the arrival of direct solar radiation. Under conditions of atmospheric stability, the UHI is more intense than under conditions of instability. EN ESTE TRABAJO SE HA EXAMINADO LA ISLA DE CALOR URBANA (ICU) DE LA CIUDAD DE SALAMANCA, ESPAÑA. COMPARANDO LAS TEMPERATURAS DE UNA ÁREA URBANA Y UNA RURAL PRÓXIMA SE HA ESTUDIADO LA EVOLUCIÓN TEMPORAL DE LA INTENSIDAD DE LA ICU PARA EL TRIENIO 1996-1998. LOS RESULTADOS MUESTRAN UNA ICU NOCTURNA POSITIVA, CUYO VALOR MEDIO MAS ALTO SE DETECTA EN OTOÑO (3.2 °C). UTILIZANDO EL MÉTODO DE SELECCIÓN DE TRANSECTOS, SE ESTUDIA LA DISTRIBUCIÓN ESPACIAL DE LA ICU. LAS TEMPERATURAS MÍNIMAS NOCTURNAS SE OBSERVAN A LAS AFUERAS DE LA CIUDAD, PRINCIPALMENTE EN ZONAS VERDES CERCA DEL RÍO. LAS MEDIDAS TÉRMICAS DIURNAS MUESTRAN UNA INVERSIÓN DE LA ICU, OBTENIÉNDOSE LAS MENORES TEMPERATURAS EN EL ÁREA URBANA, DONDE LOS EDIFICIOS, QUE HACEN SOMBRA, IMPIDEN QUE LLEGUE LA RADIACIÓN SOLAR DIRECTA. EN CONDICIONES DE ESTABILIDAD ATMOSFÉRICA LA INTENSIDAD DE LA ICU SE ACENTÚA RESPECTO A LOS CASOS DE INESTABILIDAD.Instituto de Ciencias de la Atmósfera y Cambio Climático, Universidad Nacional Autónoma de México2009-10-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://www.revistascca.unam.mx/atm/index.php/atm/article/view/8514Atmósfera; Vol. 16 Núm. 3 (2003)Atmósfera; Vol. 16 No. 3 (2003)2395-88120187-6236reponame:Atmósferainstname:UNIVERSIDAD NACIONAL AUTÓNOMA DE MÉXICOinstacron:UNAMenghttps://www.revistascca.unam.mx/atm/index.php/atm/article/view/8514/7984info:eu-repo/semantics/openAccessoai:ojs.pkp.sfu.ca:article/85142024-08-16T16:52:34Z |
