Juan G. R. Tornadoes, storms, floods and frost in USA in December 2015
Water and Irrigation Vol : 7, No. 1: 1-3, January, 2016, Spain.
Climate change in the territory of the United States, as a result of increased pollution emissions of greenhouse gases and the deforestation favors the warming and foster the development of unstable weather events that allow the formation of: droughts, storms, floods and tornadoes, high wind speeds with greatly destructive effects. The death toll in the United States amounted to 43 people as a cause of severe weather conditions prevailing during the period from 23 to 28 December 2015. The affected areas are in the Tornado Corridor as a result of tornadoes, floods and frost damage to homes, businesses, roads and power failures were reported. They have made great efforts to reduce greenhouse gas emissions and increase reforestation, but even these are insufficient to counteract the effects of climate change and the destructive tornado activity, it is recommended that reforestation in the region will increase and the s greenhouse gas emissions are reduced.
The death toll in the United States increased to 43 people as a result of severe weather conditions prevailing during the period from 23 to 28 December 2015.
On Sunday 27 heavy snow in New Mexico that left many roads cut off and frost and heavy snow in the states of Texas and Kansas were recorded. Flooding caused by heavy storms on Saturday 26 left eight people dead in Missouri and five in Illinois located in the Middle East. In the South in Dallas, Texas in 11 people were killed by tornadoes, entire residential areas were reduced to rubble and devastation extends many kilometers.
Christmas Day on Friday 25 strong storms and tornadoes killed 17 people in the states of Mississippi, Tennessee and Arkansas, in the state of Alabama, in the South East of the country region 2 people died. On December 24 in the northeastern region of the country, in the city of New York, the temperature was about 20 C. Further south, in the state of Florida, the temperature reached 28 degrees. On December 23 in the state of Mississippi three dead and over 40 injured in six counties reported after several tornadoes hit the state.
High temperatures in winter favored the occurrence of tornadoes, storms and floods, the very cold front from Alaska winter brought havoc to New Mexico and heavy snow to the neighboring states of Kansas, Texas and Oklahoma. More than 25 tornadoes were reported during the disaster, the unusual heat wave observed on the east coast of the United States contributed to the formation of tornadoes that affected states in central, south and southeast. For several days Goliath winter storm moved from the East Coast of the United States, crossing the states of the Middle East, southern High Plains and parts of the southern states west and south bringing snow, frost and strong winds, causing major disasters in its trajectory and the deaths of some 19 people.
Climate change is characterized by prolonged droughts and heavy rains that alter weather patterns, causing major disasters and floods, rising global temperatures, melting, rising sea levels and increased tropical storm activity and cyclones. Climate change in the territory of the United States, as a result of increased pollution emissions of greenhouse gases and deforestation favors the warming and foster the development of unstable weather events that allow the formation of storms, floods and tornadoes high wind speeds with greatly destructive effects.
The increase in temperature of the planet Earth is not only problem of the United States, but in different regions and all countries, as the global average temperature has risen by one degree Celsius in relation to the average temperature of the planet from the begining industrial revolution in 1850, reflecting that reduce emissions of greenhouse gases is a task for everyone.
The regions located in the central United States have more favorable for the formation of thunderstorms that produce tornadoes conditions. The Great Plains area is relatively flat and this allows the cold polar air from Canada and Alaska meets the warm tropical air from the Gulf of Mexico through the southern United States, when these two air masses meet, it is when much of tornadoes originate.
Most tornadoes in the United States are formed in an area known as Tornado Corridor. The core of this area includes parts of the states of Nebraska, Kansas, Oklahoma and Texas, gradually extending side regions of this large area as part of the states of Colorado and New Mexico to the West and the states of Arkansas, Louisiana, Mississippi and Tennessee in the South, coming from the Southeast to the states of Alabama, Georgia, Florida and South Carolina. In the side areas of the states of the bottom of the High Plains and the Southern States find the Midwestern states being the highest risk of tornadoes in Missouri, Illinois, Kentucky, Indiana and Ohio. Most tornadoes occur in agricultural and urban areas, require moisture and variability related to weather changes in the spring and summer temperature.
An analysis of the situation of storms and tornadoes formed in the damaged areas, it appears that they have originated in an area of high probability of occurrence of these phenomena is located in Tornado Corridor, the region is strongly influenced climate change and the meeting of cold polar air from Alaska with the warm tropical air. In the area they have made great efforts in reforestation, but still insufficient to counteract the effects of climate change and the destructive tornado activity, so it is recommended that the reforestation of the region should increase as a greater presence of forest area, it tends to regulate the temperature and increase the barrier of trees that mitigates the effects of wind tornadoes, as well as greenhouse gas emissions must be reduced in the fight against climate change.
If in the balance of weather affectations of the regions analyzed, we include the states located in the extreme west of the western United States, dated December 29, 2015, it shows that the states of California, Nevada and Oregon are affected by drought: exceptional, extreme and severe, according to the National Drought Mitigation US, in this situation the greenhouse gases emision and insufficient forest area favor the conditions of heat and drought. The analysis of two climate scenarios, notes that the conditions of heat, cold, frost, drought, floods and tornadoes manifest themselves according to prevailing weather conditions.
