Before I get to where I am going, FN's remarks about the meteorologists being mostly wrong in Goa contrasts starkly with their counterparts in Canada where they are mostly right. That too weather forecasting in Canada can be a pretty tricky thing since we quite steep variations in temperature during even 24 hours. For example some days in winter, morning can start with plus 5 centigrade and then go suddenly to minus 25 that afternoon or night. Mario observes: Roland, In my experience, which is EVERY DAY for some 38 years the computer assisted weather forecasting in north America is hardly accurate out to even a few days. The difference is that they revise their forecasts six or more times a day between now and then and even then their forecasts the previous night can be wrong the next morning. I agree that it is a difficult process, which is why I am skeptical when climate forecasts are made, also by computer models, out to several years if not decades, and then some governments want to make expensive policy based on these.
