According to our book, the Arctic ozone hole appears on a larger scale during cooler periods. I was wondering if these cold periods were related to the climate cycle ENSO (El Nino-Southern Oscillation) and more specifically the La Nina part of the cycle when temperatures are cooler then normal. If the ozone hole and La Nina are connected is there a way to predict when the next La Nina year is going to be and begin preparing experiments to test ways to make the hole less severe during the colder periods. These experiments could lead to possible solutions for the future when hydrogen becomes a predominate source of energy and more water is released into the stratosphere and leads to longer and more severe cooling periods and more PSCs in the air.
