Although warmer-than-average
stratospheric weather conditions have reduced ozone depletion during the past two years, the current ozone hole area is still large because levels of ozone-depleting substances like chlorine and bromine remain high enough to produce significant ozone loss.
"Whilst the occurrence of sudden
stratospheric warming increases the chance of cold weather, it's by no means a guarantee.
Describing sudden
