Global to local hydrological modelling and forecasting – virtual event

ECMWF will host a three-day virtual event titled „Connecting global to local hydrological modelling and forecasting: scientific advances and challenges“ from 29 June 2021 to 01 July 2021.

Abstract submission is open until 31 March 2021. To register or submit an abstract, please visit the workshop page.

The workshop will be organised by ECMWF, the Copernicus Emergency Management Service (CEMS), the Copernicus Climate Change Service (C3S), the Hydrological Ensemble Prediction EXperiment (HEPEX) and the Global Flood Partnership (GFP). ECMWF operates C3S and contributes to CEMS. The two services are part of the EU’s Copernicus Earth observation programme.

‘It Is All Connected’: Extreme Weather in the Age of Climate Change

(today)

The question is, how much did climate change affect this specific storm and the resulting floods?

A complete answer will have to await analyses, almost certain to be undertaken given the magnitude of the disaster, that will seek to learn if climate change made this storm more likely, and if so, by how much.

But for many scientists the trend is clear. “The answer is yes — all major weather these days is being affected by the changes in climate,” said Donald J. Wuebbles, a professor of atmospheric sciences at the University of Illinois.

Germany and Europe Floods: Live Updates, Photos and Videos

The flooding in Western Europe is a disaster of historic proportions. Satellite pictures are sometimes top-of-the-line methods to know the size of pure disasters, however after we tried it from above, all these pictures confirmed the place clouds, clouds and extra clouds. So we tapped to Finland primarily based company referred to as ICEYE. Their radar imaging know-how can see by clouds to seize in actual time the magnitude and nature of the flooding on the bottom. This is Erftstadt in Germany, one of many city’s most closely affected by the flooding.

Venice on its knees as floods devastate city

„We are faced with total, apocalyptic devastation,“ Veneto Governor Luca Zaia told Mediaset television.
„I’m not exaggerating; 80% of the city is under water, the damage is unimaginable“. Premier Giuseppe Conte is due to arrive in the city to assess the situation on Wednesday and Zaia said he would stay the night. I

Scientists link California droughts, floods to distinctive atmospheric waves

(6.4.2017) Wavenumber-5 consists of five pairs of alternating high- and low-pressure features that encircle the globe about six miles (10 kilometers) above the ground. It is a type of atmospheric phenomenon known as a Rossby wave, a very large-scale planetary wave that can have strong impacts on local weather systems by moving heat and moisture between the tropics and higher latitudes as well as between oceanic and inland areas and by influencing where storms occur.

The slow-moving Rossby waves at times become almost stationary. When they do, the result can be persistent weather patterns that often lead to droughts, floods, and heat waves.
