The Norwegian Continental Shelf (NCS), concentration of this specified e-book, is a prolific hydrocarbon area and either exploration and construction task continues to be excessive to today with a good construction outlook. A key aspect this present day and sooner or later is to couple technological advancements to bettering our knowing of particular geological events.
The booklet goals to provide the original geomorphological landscapes of the Czech Republic. The geomorphic strong point of this state merits from the proximity to 2 precise ecu geological domain names: the outdated cratonized Bohemian Massif and the fairly younger Tertiary fold and thrust belt of the Western Carpathians.

Katabatic winds affect only the first few hundred metres above the ground and their velocity is proportional to the steepness of the underlying terrain. The minimum velocity therefore coincides with the top of the inversion layer, and the strongest winds occur in coastal escarpments with very steep slopes, smooth ice surfaces (minimum turbulence) and a topography which channels the katabatic outflow into small stretches (Parish 1988). It has been suggested (Radok 1973) that the continental drainage flow is also accelerated by the replacement of relatively warm air by cold air moving downslope and by sublimational cooling of drifted snow.
The South Pole has been cooling slightly since 1976, and Dutton et al. (1991) pointed out an increased cloud cover in January–February from 1976 to 1985, while summer insolation partially recovered in the period 1986–1989. Neff (1992) suggested that cooling could be related to the beginning of spring depletion of stratospheric ozone, which may reduce the stability of the stratosphere and allow warm, moist air to reach the plateau. Unfortunately, the processes linking changes in surface air temperature to variations in tropospheric and stratospheric circulation are particularly complex, and they are largely unknown in Antarctica because of the sparse radiosonde network.
In general, the difference between precipitation and evaporation/sublimation shows a broad winter maximum and a summer minimum (Bromwich and Parish 1998). 22 R. 5 Wind Regime Since early exploration, one of the most impressive aspects of the Antarctic climate has been the strength and persistence of winds. Most surface winds blowing over ice sheets are katabatic winds generated by the outward and downward flow towards the coast of cold, dense air masses from the boundary layer of the interior of Antarctica.
