Wet and Wild Weather

Weather has been nuts here in the US lately. I did a little digging and found some information that gives a real visual on how off things are this year.

Yesterday (June 23) the city of Cincinnati (recorded at CVG) officially topped the average annual rainfall total and we still have six more months to go. The official annual average is 39.57 inches. We are now at 40.32 inches. I can't even imagine what the numbers must be like out West in the Plains:


The next chart is a track of US tornadoes since 1950. There is a small fault to this chart as the ability to track and verify separate tornadoes wasn't that good until about 20-30 years ago. Still, the past few years are still good and you can see the same effect that we saw in the rainfall totals. We are already ahead of last year's total and about 500 tornadoes behind the record year of 2004. That might seem like a lot but it should be noted that hurricanes and their leftover low pressure systems will spawn a number of tornadoes even though "tornado season" is essentially over:


According to NOAA, we are currently tracking over 200 tornadoes ahead of the high end curve of the prediction charts. If that number holds, we'll end the year with nearly 2,100 tornadoes in the US.

Lastly, there are earthquakes. This data from USGS goes up to June 22 and only covers major quakes (5.0+) but it's still impressive:


Thankfully we are roughly in line with average on the 7.0-7.9 and 8.0+ as we have had 8 and 1 respectively so far this year. The 5.0-5.9 and 6.0-6.9 are well above average though. Some of this is directly due to the Japan quake and earthquake accumulation is distinctly not linear. Still it's rather disconcerting to see that our earthquake totals for the first six months are already above the total numbers for 2001-2003. It seems highly likely that we will top the 2007 total of 2,270. Were the Earth to get another large quake (and with the volcano activity, that seems possible), it would push things well past that number and possibly close to the 3,000 range.

Just one item would be enough for one to sit up and take notice, but all three grab one and shake them somewhat. There is probably some sort of cause but whether that is solar actively or magnetic and gravitational shifts in the solar system, I couldn't say. Either way, let's hope this ride slows down before it gets any bumpier.
