ANOTĀCIJA
Promocijas darba „Gaisa temperatūras un atmosfēras nokrišņu mainības
raksturs Rīgā” mērķis bija veikt gaisa temperatūras un atmosfēras nokrišņu vidējo un
ekstremālo radītāju ilgtermiņa pārmaiņu analīzi Rīgā, balstoties uz izveidotām
homogēnām diennakts vidējās, maksimālās un minimālās gaisa temperatūras un
diennakts atmosfēras nokrišņu novērojumu datu rindām novērojumu stacijai Rīga-
Universitāte.
Pirmo reizi Latvijā analizēta gaisa temperatūras un atmosfēras nokrišņu
ilggadīgo novērojumu datu homogenitāte, noteikti neklimatisko faktoru ietekmes
rādītāji. Klimata apstākļu mainība Rīgā raksturota, balstoties uz ilggadīgākajiem
meteoroloģisko novērojumu datiem Latvijas teritorijā, kas līdz šīm klimata pētījumos
nav izmantoti. Gaisa temperatūras un atmosfēras nokrišņu pārmaiņu izvērtējums veikts
izmantojot 16 gaisa temperatūras un 9 atmosfēras nokrišņu vidējo un ekstremālo vērtību
indeksus.
SUMMARY PhD thesis „The character of variations in the air temperature and precipitation in Riga” was aimed at the analysis of the air temperature and precipitation in Riga based on the homogeneous daily mean, minimum and maximum air temperature and daily precipitation data series of the meteorological station Riga-University. An exhaustive analysis is provided of homogeneity of long-term air temperature and precipitation data series as well as the identification of the effect of non-climatic factors. Analysis of the air temperature and precipitation in Riga was carried out based on the longest meteorological data series available that had not ever been used before in climate studies. 16 air temperature and 9 precipitation mean and extreme indices were employed in the evaluation of the variations in the air temperature and precipitation.
