Weather generators provide synthetic daily values of meteorological variables, statistically equivalent to observed local series of those variables. Weather generators – Procedure The IPCC suggests considering weather generators for climate impact assessments, pointing out the conditions of their use. Weather Generators are not forecasts, but tools to assess the impacts of climate … [Read more...] about Weather generators: Estimating climate impacts
Combining seasonal forecasts with weather generators is a suitable approach to estimate climate risks for the coming weeks or months.Local climate variability depends on global climate patterns, thousands of miles away.Some of those “teleconnections” are persistent, recurrent and covering a wide spatial scale, such as whole continents or even larger areas.Perhaps the most important climate pattern, significantly influencing global climate … [Read more...] about Seasonal forecasts and climate-variability impact assessments
Usually, climate means the statistical average weather over a 30-year period. Instead, climate variability refers to dispersion around those means, generally at local scales and for shorter periods. The latest IPCC Working I report summarizes some evidence about increasing climate variability. The IPCC report particularly focus on the increase in the frequency and strength of extreme events.IPCC also released a … [Read more...] about Climate Variability and risk assessments
The Climate Change scenarios come from simulations with Global Climate Models (GCMs). Current GCMs simulate mass and energy exchanges between ocean, land, and the atmosphere. Simulations come to each 250-600 km2, according to the climate model spatial resolution. The GCMs usually consider 10-15 vertical layers.Relevant centres in the USA, UK, Germany, Russia, France, Canada, China, Australia and other countries … [Read more...] about Climate Models and available climate scenarios
