Description
Summary:The view of existing tendencies in climate changes proposed by the authors is based on the available facts. Earlier, cyclic behaviour of the world's river flows was discovered, which was found to correlate with the cycles of solar intensity. Similar correlation was revealed by the authors for global temperature anomalies. Based on the wavelet analysis it became possible to notice a phase inversion in these processes, which, in the authors' opinion, could be associated with re-magnetisation of the Sun. This, for example, explains the hitherto inexplicable interruption in the temperature rise during the 1950-70-ies. The authors stress that the processes of global climate changes are of ambiguous character, being consisted of the natural and the anthropogenic components. Publikācijā autori, balstoties uz pieejamiem faktiem, parāda klimata izmaiņas tendences. Līdz šim, pētot upju caurplūdumus, tika pielietota spektrālā analīze, kura ļāva atklāt šo parādību ciklisku raksturu. Salīdzinot to ar Saules intensitātes analīzes datiem, atklājas interesantas likumsakarības. Analogiska pieeja izmantota, analizējot temperatūras izmaiņas. Pateicoties veivletanalīzei, izdevās atklāt procesa fāzes apvērsumu, kas, pēc mūsu domām, ir saistīts ar Saules pārmagnetizēšanos. Tas izskaidro līdz tam nesaprotamu temperatūras paaugstinājuma pārtraukumu no 1950. gada līdz 1970. gadam. Analizējot šīs parādības, uzmanība vērsta uz procesu izmaiņu divslāņaino raksturu, kas sastāv no divām komponentēm - dabiskās un antropogēnās.
