The partial differential equations that describe the behavior of fluids, like the atmosphere and water - the equations of fluid dynamics - are inherently unsolvable. It's like 18 equations in 20 unknowns (IIRC). The only way to solve a system of these is to assign initial conditions to some of the equations, creating a boundary condition.
The US Drought monitor shows that our friends in the middle of the country, from Indiana, Kentucky and Tennessee west through much of the bread basket of the US are suffering a serious drought. The map shows the broad reach of the severe to exceptional drought. Friends and family in this region are relaying temperatures in the upper 90s to over 100. I don't need to tell you these are extremely unusual events up there. Just as strangely, here in the Silicon Swamp, the summer has been mild and wet. Yes, it gets into the lower 90s here, but days like yesterday, when it starts raining early and stays cloudy all day, our high was 85. The month of June had an average high temperature almost a full four degrees cooler than average, and a rainfall one and half inches wetter than average.
The vagaries of weather. Strange that it should be hotter in Hoosieropolis than Florida, but it has been.
I've quoted Dr. Ryan Maue at Florida State University before, a young Ph.D. studying tropical weather systems. I dropped by today to see if there was anything going on in the tropics to be aware of, and found this interesting item:
March 2012: Another record falls... La Nina causes record suppression of global tropical storm numbers ...The lowest number of storms in two calendar years and in 24 continuous months. Bear this in mind the next time you come across someone saying that global warming or whatever they call it this week is causing more hurricanes and more severe hurricanes, direct them to Dr. Maue.
The last two calendar years saw a total of 146 global tropical cyclones, the lowest 2-year total in records since at least 1970. In the past 24-months, including ongoing Southern Hemisphere tropical cyclone activity, there have been a total of 141 global tropical storms. This is also a record low.
This, too, is the vagaries of weather.
