ENSO 2015 forecast
The climatic cycle known as the El Niño Southern Oscillation, or ENSO, exerts a powerful but irregular influence on weather around the world. Climatologists predicted that 2015 could be a record year for El Niño, given surface water temperature warming in the eastern equatorial Pacific Ocean — one of the key indicators of the cycle. Its impact in Wisconsin is indirect but causes general warmer conditions in winter — while other parts of the world can see droughts, floods, and massive food insecurity. But El Niño can still cause challenges for Wisconsin farmers, tourism, logging, and wildlife. The cycle is highly unpredictable, and scientists are still trying to understand how it interacts with global climate change.More
Wisconsin experiences all four seasons in their full intensity, sometimes even within a few days of each other. This pattern reflects a classic example of a continental climate, a classification applied to regions of the globe with hot or warm summers and cold winters with average temperatures often below freezing. More specifically, Wisconsin has a humid continental climate, and straddles the border between its hot and mild summer subtypes. What this means over the summer season is that many areas of the state can have temperatures high enough to be dangerous — to humans, to animals and even to plants. When the mercury rises, though, people can take action to protect lives and property.More
