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.
