Phi for All Posted January 2, 2015 Posted January 2, 2015 Are you looking for ways that studying past weather events can help us to devise better methods for dealing with them?
hypervalent_iodine Posted January 2, 2015 Posted January 2, 2015 Could you be more specific? 'What can be learnt?' is a little vague and would encompass too big a list for it to be useful to you. It depends on a lot of things, like how new the affected area is, how many people are there, if they have a history of bad storms, what type of storm it is, etc. I live in the sub-tropics, where there are realistically only two seasons: hot and stormy and not as hot and stormy. We are pretty well versed in how to prepare for and deal with storms in the summer months, but we are always finding new ways to improve. This is especially true as climate global warming its mark more apparent and the storms we get are more violent and out of the ordinary. One big thing that is often learnt in the aftermath is that insurance companies are not your friends and always make sure you have proper storm and flood coverage. I would think that many places build to withstand local whether events and the like so as to minimise damage, though technology is always improving. In New-Zealand, for example, many buildings are built to withstand the constant barrage of earthquakes the country received and here in Queensland (Australia), houses are built to stay cool in the summer and not get blown away during storm season. 1
studiot Posted January 2, 2015 Posted January 2, 2015 The trouble with 'homework help' is that it does not tell us what subject the question is in or at what level. So is this geography, politics, an English essay, general science or what, and at what level? Help us to help you. 1
Harold Squared Posted January 25, 2015 Posted January 25, 2015 What can be learned? Do not build on the coastlines or in the North American areas prone to tornadoes. Have people learned this lesson? Obviously not. The good news is that storms are NOT getting more severe or frequent on average considering the historical record.
iNow Posted January 25, 2015 Posted January 25, 2015 http://www.nature.com/ngeo/journal/v3/n3/abs/ngeo779.html Whether the characteristics of tropical cyclones have changed or will change in a warming climate — and if so, how — has been the subject of considerable investigation, often with conflicting results. Large amplitude fluctuations in the frequency and intensity of tropical cyclones greatly complicate both the detection of long-term trends and their attribution to rising levels of atmospheric greenhouse gases. Trend detection is further impeded by substantial limitations in the availability and quality of global historical records of tropical cyclones. Therefore, it remains uncertain whether past changes in tropical cyclone activity have exceeded the variability expected from natural causes. However, future projections based on theory and high-resolution dynamical models consistently indicate that greenhouse warming will cause the globally averaged intensity of tropical cyclones to shift towards stronger storms, with intensity increases of 2–11% by 2100. Existing modelling studies also consistently project decreases in the globally averaged frequency of tropical cyclones, by 6–34%. Balanced against this, higher resolution modelling studies typically project substantial increases in the frequency of the most intense cyclones, and increases of the order of 20% in the precipitation rate within 100 km of the storm centre.

Obviously not. The good news is that storms are NOT getting more severe or frequent on average considering the historical record. Evidence, please. Because "once-in-five-year" instances of heavy precipitation has been increasing for several decades. Winter storms have been increasing in frequency and intensity. http://nca2014.globalchange.gov/highlights/report-findings/extreme-weather http://www.ucsusa.org/sites/default/files/legacy/assets/images/gw/Precipitation-Change-Map.jpg Heat waves are getting more severe http://www.ucsusa.org/global_warming/science_and_impacts/impacts/global-warming-and-heat-waves.html#.VMauuShQmao Which makes me doubt a bald assertion that nothing has happened.
