Document Summary
La nina: cooling of water in tropical, eastern specific: index value: it"s a 3 month mean . 5 to . 9 is weak, 1. 0 to 1. 4 is moderate and over 1. 5 is strong. Walker circulation: rising to sinking air, warm to cold water. Heat is taken from the environment: melting, evaporation, sublimation. Heat is released to environment: condensation, freezing, deposition. Latent heat: hidden warmth: vaporization, fusion: from solid to liquid and vice versa, sublimation: solid to vapor and vice versa. Water vapor content: humidity: absolute humidity: mass of water vapor/ volume of air, decreases as volume increases, specific humidity: doesn"t change as air rises and descends, mass of water vapor/total mass of air.
