The influence of ENSO on South Africa winter rainfall

2011

International audience; We analysed the relationship between El Niño Southern Oscillation (ENSO) and South Africa austral winter rainfall using a 682 raingauges daily rainfall database documenting the period 1950-1999. The May, June and July (MJJ) seasonal rainfall amount shows a positive correlation with the Niño3.4 index that becomes significant since the mid 70's. Wet spells properties (length, frequency and intensity) at the raingauge scale indicate that high (low) MJJ seasonal rainfall amounts recorded during El Niño (La Niña) events are the result of longer (shorter) wet spells in the Cape Town area and more (less) frequent wet spells north of 33°S. Wet spells with daily rainfall amou…

Inferring phytoplankton community composition with a fatty acid mixing model

2015

Abstract. The taxon specificity of fatty acid composition in algal classes suggests that fatty acids could be used as chemotaxonomic markers for phytoplankton composition. The applicability of phospholipid-derived fatty acids as chemotaxonomic markers for phytoplankton composition was evaluated by using a Bayesian fatty acid-based mixing model. Fatty acid profiles from monocultures of chlorophytes, cyanobacteria, diatoms, euglenoids, dinoflagellates, raphidophyte, cryptophytes and chrysophytes were used as a reference library to infer phytoplankton community composition in five moderately humic, large boreal lakes in three different seasons (spring, summer and fall). The phytoplankton commu…

Tūrisma sezonalitāte Jūrmalā: mazas viesnīcas piemērā

2020

Bakalaura darbs “Tūrisma sezonalitāte Jūrmalā: mazas viesnīcas piemērā” ir balstīts sezonalitātes izpētē un ietekmē uz tūrisma nozari. Darbā detalizēti tiek aprakstīts kā tūrismu ietekmē sezonalitāte un tās saistība ar citiem faktoriem. Pētījuma mērķis ir izvērtēt sezonalitātes ietekmi uz tūrisma nozari Jūrmalā, balstoties uz konkretas mazās viesnīcas apmeklētāju dinamikas datu analīzi laika periodā no 2010. līdz 2019. gadam. Zinātniskā literatūras analīzes rezultātā tiek aprakstīta sezonalitātes teorētiskā puse un tās ietekme uz viesnīcu, restorānu, u.c. tūrisma nozaru darbību, kūrortpilsētas piemērā - vasaras un ziemas sezonās. Pētījuma tēma tiek izvērsta Latvijas tūrisma vēstures kontekt…
