    Sammanfattning : The aim of this study was to examine the infiltration rate of water and some parameters affecting it. Especially the land usage, the abundance of roots and macropores were investigated. A field study was carried out on western Java in Indonesia, on the slope of Mount Salak. The study compared four different land uses; i. LÄS MER

    Sammanfattning : This paper is a literature study aiming to describe scientists newest theories and knowledge concerning the El Niño and Southern Oscillation. Firstly I have described the ”normal” conditions with rising and sinking air in Hadley- and Walker-cells in the equatorial Pacific and from there moved on to explaining the reversed circulation patterns and higher sea surface temperatures (SST) leading to rising air and anomalous precipitation in eastern Pacific constituting the El Niño phenomenon.
