Tornadoes and Hurricanes of 2000-2013
This blog is mostly for the storage of these charts and any more that I make. Both charts show the number of the chosen weather phenomenon per the given time period. The tornado chart shows the number of tornadoes every year from 2000 up to 2013. The 2013 tornado season has barely gotten started with 77 tornadoes already confirmed. More tornadoes are expected later today(Thursday) in Texas and Louisiana. Other areas in the deep south will receive flooding rains, hail, and damaging winds. Most of the Plains and Mid-west will see either a wintry mix or all snow even, but that is to be discussed in a blog later in the morning. The main problem should be instability, but the NAM and GFS have been showing an increase in CAPE. If this active storm pattern continues throughout the spring, then there will be problems. Each storm system has a strong low-level jet(LLJ), good directional shear, good helicity and other dynamics, just instability has been lacking to create a monster event. Once we get into spring and the CAPE issue is gone, then there could be major problems in the south and southern plains if the active pattern continues.
The tornado chart shows the number of tornadoes from 2000 to 2013. There have been many ups and downs and extremes in these past seasons. Some years, like 2002 and 2012, where relatively quiet in tornado activity. 2012 was one of the quietest seasons on record, despite an active start. On the other hand, there are seasons like 2004, 2008, and 2011 that were very active. 2004 holds the record for the most tornadoes and 2011 broke many tornado records. The April 25th-28th outbreak and the May 21st-26th outbreak sequence were the notable outbreaks of that year. The two most notable tornadoes, at least in my opinion, of 2011 were the Tuscaloosa-Birmingham EF4 tornado and the Joplin EF5 tornado. Both events caused massive amounts of loss of life and tornadoes. The memorable outbreak of 2004 was the May 2004 outbreak sequence which included 2 F4's. 2004 was the third most active tornado year in terms of number of tornadoes, only behind 2011 and 2004. Some of the most memorable outbreaks and tornadoes were the Super Tuesday outbreak and the late-May 2008 tornado outbreak sequence, including the Parkersburg EF5 tornado. Something with late May and tornado outbreaks goes together, huh. Of course there have been other significant tornadoes I have not mentioned, like the Greensburg EF5, El Rino EF5, April 27th EF5's, etc, but you basically know what happened there. For 2013, the season has barely got underway. We have already had one EF4 (Hattiesburg, MS) and one EF3 (Adairsville, GA) cause major damage. Hopefully we don't have a record year, but just in case we do, people should prepare for the worst.
The hurricane chart shows the amount of Atlantic tropical depressions(TD), tropical storms(TS), hurricanes(H), and major hurricanes(MH) from 2000 to 2012. The 2013 hurricane season has not started, and will not start for a while, so it is not included in the graph. Just like for tornadoes, there have been many extremes since 2000 for hurricanes. We have seen some of the most destructive/deadliest hurricanes on record, the most active seasons on record, and a couple quiet seasons thrown in there. 2005 and 2004 were both really bad years in terms of hurricanes striking the US, along with 2008, 2012, and 2003. 2005 had the storms of Dennis, Katrina, Rita, and Wilma make landfall in the United States with other hurricanes elsewhere. The 2004 season featured Charley, Frances, Gaston, Ivan, and Jenne make landfall in the Untied States with other hurricanes elsewhere. These two years would leave lasting scars along the gulf coast from some of the most memorable hurricanes in history. 2008 had hurricane Humberto and Ike make landfall on the Texas coastline, with Ike being was worse. 2003 had Cluadette and Isabel hit the US, Isabel being more intense and causing more damage. In 2012 two category one hurricanes would make landfall in the US, both causing over $1 billion in damage. These two hurricanes were Isaac and Sandy, with Sandy as the second costliest hurricane on record. I know Sandy was post-tropical at landfall, but she still caused tons of damage and the average person isn't going to care if she was tropical or post-tropical. Both Isaac and Sandy had one thing in common, they both had high storm surge and large wind fields. Their winds, however, weren't to strong which caused them to be cat 1's at landfall. Still, they caused a lot of damage and loss of life in the Atlantic basin. With all of this action you think there would be a break somewhere, right? Well, 2006 and 2009 both had below average activity, 10 named storms for 2006 and 9 named storms for 2009. The number of hurricanes and major hurricanes were also lo for these years, as were US landfalls. What about the 2013 season? We haven't reached June 1st yet, so the season hasn't started. These next few weeks will be important however as if the we get a negative NAO setting up the winds over the Atlantic should lessen allowing the waters to warm. This is being shown on the models. Also we will start to get a better idea of how enso will affect this season. Hopefully this season isn't another 2005 but people need to always be ready for hurricanes.
Have a great night/morning and I will hopefully have a blog update on the severe weather and winter weather that is affecting the US.
