Scripps Institution of Oceanography in San Diego, USA, suggested that the nature of heat waves in North America is changing. And the reason for this was nothing like global warming.
First, during heat waves observed increased nocturnal air temperature and humidity of the bulk of it in the dark. Furthermore, the mid-summer heat waves have become more severe, especially in the cool coastal regions.
Since coastal ecosystems respond to changes in temperature is more painful than continental, discovered the thermal waves can strongly affect the normal life of the residents of California, who are used to average temperatures and cool nights. Residents need more air conditioners and other appliances for the climate-control system, in which they had little need. Would follow the change in electricity demand. High humidity combined with the heat will certainly affect the health status has not been acclimatized 21 million Americans living on the coast and the flora and fauna. Moreover, addiction can cause not much physiological, and psychological difficulties.
Classical heat wave on the California coast occupied the territory in the desert areas and valleys, where the day was hot, and the night is cool and dry. In the next few decades, the staff expects increasing night temperature and humidity to further increase the intensity of heat waves. Interestingly, the same phenomenon in the desert areas will lose its strength against the general warming in the state.
