Air and Water

Starting by considering air and water in equilibrium (i.e., at rest), it progresses to discuss dynamic phenomena first focusing on large scale structures, such as El Nino or trade winds, then on ever smaller structures, such as low-pressure zones in the atmosphere, clouds, rain, as well as tides and waves.

Incepand prin a considera aerul si apa in echilibru (adica in repaus), progreseaza pentru a discuta despre fenomenele dinamice, concentrandu-se mai intai pe structuri la scara larga, cum ar fi El Nino sau vanturile alice, apoi pe structuri din ce in ce mai mici, cum ar fi zonele de joasa presiune din atmosfera, nori, ploaie, precum si maree si valuri.
