EARTH 20 Lecture Notes - Lecture 12: Joule, Sensible Heat, Latent Heat
Document Summary
How earth"s energy balance and energy exchanges produce climate and weather. Interaction of energy and the earth"s spheres . Weather: response of the earth system to energy imbalances (day-to-day stuff) Ex. weather change: major storm one day in an otherwise dry region (but rainstorm was just a one-time event) Climate: regional or worldwide distribution of temperature, precipitation and storm patterns (the long-term average of weather) Ex. climate change: dry region (dry climate) starts to experience regular rain storms > shift in climate (change in daily weather patterns over long term) Follow money: banks don"t delegate sums of money for no reason. Lloyds of london: major international bank that set up separate arms/branches to explore effects of climate change on insurance/reinsurance industry. Kinetic energy: energy of motion ( ex. Heat energy: energy of random motion of atoms and molecules. Sensible heat: heat that can be measured. Latent heat: heat absorbed or released at phase change.
