ESS105H1 Lecture Notes - Lecture 9: Sea Breeze, Rain Shadow, Cool Air
Document Summary
Weather: the state of the atmosphere at a specfic time (i. e. short-term variations) Considering this, one isolated event might be normal (e. g. heat wave); however, more instances of these isolated events suggest there is a change in climate. Global warming (gw) is an increase in the global avg surface temperature-not to say all areas of the earth will warm at the same rate: global warming is an indicator of climate change. Climate change refers to a broad range of global phenomena created mostly by burning fossil fuels which add heat by releasing green house gases (ghg: north pole/arctic are most affected by gw. Controls on climate change: local and regional wind. Local winds: sea breeze (daytime): land heats up significantly faster than water. Hot air over land rises and cooler air over water sinks: land breeze (nighttime): land cools down significant faster than water.
