Pretty sure C) the Rio Grande.
Weather is a complex phenomena. in order to solve engineering problems such as the prediction of weather, we utilize degrees of freedom (DoF)... weather is one of the many elements that need millions of DoF and still cannot accurately predict it. mainly it's a vector analysis much akin to finite element analysis where each micro degree of freedom or say molecule of air is represented as one point interconnected in a web of points and each point's properties are altered relatively (similar principles how autonomous mini drones coordinate synchoronously) to each other.
many factors are considered: pressure, temperature and density of the air for sure. friction factors. drag factors. rotation of the earth. and that's the natural phenomena. include the heat given off the land, the radiation from the sun, airplanes, people, etc... its highly complicated. having done a weather station project, it's fair to say that there isn't a simple answer to your simple question. we measured wind direction, wind current, temp and humidity, visibility, pressure, etc... and we couls measure these things, but can't really say why say the wind went east or west... except tell you that its because of millions of degrees of freedom interacting with each other simultaneously and some things like weather are just like that.
Answer:
7.798
Explanation:
It is understood that as at 31 December 2018, there had been 150 tornado event days with 1169 total tornado reports for 2018.
Then the average will be a calculated as:
1169/150= 7.79. This is regarded as the average amount of tornado experienced in the days it took place.
We can then infer and say that on average, each tornado event day had about 7.79 tornadoes reported.
