At what temperatures are certain weather events expected to occur?
Looking at the points you mentioned. – In Africa. Especially in NE Africa there continue to be drought. This is now thought to be a result of climate change bought on by global warming. – record rains Almost every year, there is some place on earth that sets a record for heavy rain fall. This is only what we would expect. However, climatologists are predicting that “extreme” weather events (storms, droughts) will become more common as a result of global warming. – A series of unusually cold winters has gripped the American Far West, while New England and northern Europe have recently experienced the mildest winters within anyone’s recollection. The weather is a highly variable phenomenon. Variations from one year to another are to be expected. However, we can expect a warmer average temperature than we had say 100 years ago. Comments for extreme weather events also apply here. – collision of air masses That is the process underlying all weather phenomena. – many seemingly contradictory
Changes in precipitation patterns happen with changes in temperature (it would seem your reference to 70’s shows that) I am not aware of any scientist who has said WEATHER is predictable there are many variables but as always you fail to see the difference between CLIMATE & WEATHER. The predominate issue is ‘change in climate’ will change weather there is no way round that, how much is not certain as is how different regions will be affected, but given we live in a system which works on the way things currently occur (on average) it is our food supplies that will be affected by any change even a fairly small one. On a smaller scale the Hurricane season is a fine example, nobody can tell you what city in the US might be hit by a hurricane (although they can be reasonably sure which region) in any given year, but they can tell you approximately when the season will start and end as the formation of such systems is seasonal (temperature driven) and the strongest events are linked strongly
