There will be less snowfall and less storage of water as snow as temperatures rise. The Earth’s atmosphere comprises various strata as it moves away from the. While some are normal, others include earthquake, volcanic eruptions, or tsunami are considered as disastrous. Mostly due to local variations and imbalances of temperature and density, ie wind, which always go areas air cooler, dense air to areas warmer and dilated. Simple natural phenomena include everyday weather that we feel, sunrise and sunset that can be seen, biological process, geological process, physical process and many others. Thus, the Governor declared a drought emergency and required every major water provider to put into place water use restrictions and conservation incentives.Īs time goes on, Californians can expect more extreme weather events: long dry periods, heat waves, low precipitation followed by more severe storms and flooding and storm surge. Atmospheric phenomena, or meteorological phenomena, are all events that take place in the Earth ‘s atmosphere. There was no spring snowpack to get California through the dry months and future dry years. Higher temperatures and rain resulted in much runoff evapotranspiration by plants. This means that high temperatures in the Sierras during winter, influenced by climate change, produced rain rather than snowpack. In the 2011-2014 statewide drought, climate scientists detected a “climate change” thumbprint on the drought. Weather in California has always been highly variable in terms of precipitation, temperature, size of storms and wind events. Even as the 2018-2019 rainy season progresses, with higher than average precipitation and colder temperatures with substantial snowpack, San Diego County and parts of Riverside and Orange County remain in moderate drought with much of the state still abnormally dry. During these long years, the Southern California region learned to rely more on highly treated wastewater for recycling and began to scale up local stormwater capture projects. Los Angeles and much of Southern California continued to be dry from 2016-2017. So, not only will it be difficult to hear coming, it will hit harder too.Extreme Weather in California and Climate Change: Droughts and FloodingĬalifornia was in drought from 2006-2009, and then again for another three years, from 2011 to 2014. There’s also a good chance that any lightening in these storms will have a positive polarity, often a sign that it will be more destructive than negatively charged weather. Due to the low cloud cover and acoustic dampening effects of snow, thunder in this kind of storm can usually only be heard if you’re near it: 3-5 km away. Once again, these effects are most common near the great lakes so, if you’re having a lakeside winter escape, beware of the extreme wind chills and frostbite that are common during thunder snow.

Thunder snow goes hand-in-hand with storms and blizzards and frequently has winds with tropical storm force. Big deal, right? RIGHT! Due to the weather conditions that are usually necessary to achieve the rarer thunder snow effect, it is usually accompanied by heavy snowfall (5 to 10 cm per hour) limiting visibility severely, even in light winds. Thunder snow is a type of thunderstorm where, instead of rain falling with the lightening, you get snow. There’s less than 6 inches of insulating snow cover.Temperatures drop from above zero to sub-zero very quickly – usually within 16-48 hours.The ground must be thoroughly saturated, usually from a heavy rain or meltwater.The great lakes region and St Lawrence River corridor are especially prone to them thanks to their habit of rapidly changing temperatures. In these cases, it’s a cryoseism.įrost quakes are most common in the eastern provinces but have been known to occur as far west as Calgary. The strain can be released by melting, but if the environment cools rapidly, it can become too much for the rock/soil to handle. When water freezes it expands (hopefully not damaging anyone’s pipes!) and builds tension in the ground. These events occur when water freezes in large areas of soil or in solid rock. In fact, the shaking has been known to register as a VI on the Modified Mercalli intensity scale.įrost quakes affect a much smaller area than earthquakes and sometimes are preceded by Earthquake Lights. Booming sounds, cracks appearing in the ground, shaking and tremors can all accompany a frost quake. Also known as ice quakes, or (if you’re feeling fancy) cryoseisms, frost quakes create many of the same signs as larger scale earthquakes.
