The Formation of Syclones dan anticyclones
A. Jet stream begins to undulateB. Rossby waves begin to formC. Waves strongly developedD. Cells of cold and warm air bodies are formed

Weaher and ClimateWhat is weather? What is climate? What is the difference?
Weather is locally, a certain short term atmosphere conditionClimate is combination of weather in a certain place for along term. Short term versus long term---that is how they differ
