Effects of the El Niño / Southern Oscillation on the climate of New Zealand
Brambus, Ondřej ; Huth, Radan (advisor) ; Müller, Miloslav (referee)
The climatic phenomena El Nino, Southern Oscillation (SO), their interaction (ENSO) and effects of ENSO on the climate of New Zealand is investigated in this bachelor's thesis. The thesis is divided into three parts. The first one (chapter 3) explains the terminology, general connections and conditions favorable for origination of an ENSO event. The second part (chapter 4) summarizes the main research related to ENSO effects on the climate of New Zealand. In this part not only meteorological and climatological studies are mentioned, but also hydrological or dendrochronological studies. The last part (chapter 5) is based on my research which examines influences in SOI (Southern Oscillation Index) changes to temperature and precipitation variables in New Zealand. During El Nino events the yearly temperature amplitude in Northern part of North Island of New Zealand tends to be bigger than the amplitude during La Nina events. This conclusion is based on correlation analysis between SOI and temperature datasets. Impact of SOI changes on precipitation variability was not confirmed.

El Niño / Southern Oscillation and its geographically remote manifestations
Navrátil, Jiří ; Huth, Radan (advisor) ; Müller, Miloslav (referee)
In the introductory part, a brief review of development of ENSO research is given, together with different ways of ENSO definitions. A basic description of the mechanism through which ENSO influences climate in the Pacific region follows. Summary of ENSO-related climate anomalies in different parts of the world as described in literature constitutes crucial part of the work. The latest related literature was preferred to be used in this part. In the second part, the ENSO influence on precipitation on the Iberian Peninsula is illustrated using correlation coefficients between values of Southern Oscillation Index (SOI) - one of the possible ENSO indicators - and monthly mean precipitaion anomalies from January 1966 and December 2015. The results are discussed with related literature used in the previous part of the work.
