Let's talk about weather
by Milota Sidorova


Surely you've been in a situation when instead of sunny day the weather forecast reported you ended up wet and cold. Surely you've been angry on meteorologists and „Higher Will“ when the weather just twisted and turn. But more weather forecasts I see, the more I notice kind of reluctant answers of meteorologists who are bit conservative to say „yes, it's going to be sunny day with some minor rains in the evening“. They don't want to tell it, since projecting rains or worse – hurricanes and tropical storms is like „projecting a nightmare“.First forecasts were based on intuition and experiences of our ancestors, based on changing of a! ll four seasons, animal migration, color of the sky, even my grandfather was able to forecast the next day. But this has changed, our climate is changing and we are experiencing more extreme weather situations latests seasons. We've got more extreme hot days, then cold periods in the middle of summer, floods and earthquakes followed by tsunami and the number of tropical storms is increasing. Although meteorologists possess high-tech computer models, it's not easy to predict the track of such storm, since it is not one line you draw on the map. But the certainty is increasing – today we can be warned one or more days in advance in case something like this appear. For instance, three day forecast in1980 was as just as „here it comes“, almost thirty years ago, meteorologists are able to track the storm within 53 miles diameter. Models and data projections will progress in the future and assure more specific projections, but as Timothy Schott, a tropical cyclo! ne program leader for National Weather Service suggested ̶! 2;the we ather was not an algebra question with only one right answer.
