Barometer Conversion Excel Chart

says:
Below and Attached is an Excel spread sheet of Barometer Conversions with Related Facts as to Major Hurricane and Tornado Events in the US. I find the conversions fairly useful as I'm more understanding of pressure readings in Hg since that's how my barometer displays, but weather is generally reported in MilBar / hPa, also have included formula's to transfer one to another.
I also found it interesting how close we as humans are to potential disaster day by day. I've been following the barometer since I read and posted some time ago a weather description, (writer un-known) that had done some major personal research on Large Mouth Bass' Barometric Comfort Zone and established at 29.98" to 30.02" Hg. Then I've found it to be most profound and every-bit as meaningful as the solunar tables.
I have been tracking my local METAR Weather Station ( http://weather.gladstonefamily.net/site/KMEM ) that provides historical data that can be placed into Excel Spreadsheet and better diagnosed.... My post mortum has indicated the local average since December '11 to today Feb 12, '12 some + 2,000 hourly readings, to be 30.10..... averaging 00.08 higher and apparently the Lg Mouth Bass have fully cooperated in not biting.
Being able to work with this data in Excel, has allowed me to plug into the hourly weather data, our very own Fishingreminder.com's Major and Minor times, and Luck being with me on this.... wouldn't you know that for every good time, (understanding it's winter) the barometer has been pretty much off the chart. Never the less..... INTERESTING....
I enclosed my local web address, located at Memphis International Airport, hopejully if you're interested you might find a weather center close to you, should you be interested in following historic trends....

I also found it interesting how close we as humans are to potential disaster day by day. I've been following the barometer since I read and posted some time ago a weather description, (writer un-known) that had done some major personal research on Large Mouth Bass' Barometric Comfort Zone and established at 29.98" to 30.02" Hg. Then I've found it to be most profound and every-bit as meaningful as the solunar tables.
I have been tracking my local METAR Weather Station ( http://weather.gladstonefamily.net/site/KMEM ) that provides historical data that can be placed into Excel Spreadsheet and better diagnosed.... My post mortum has indicated the local average since December '11 to today Feb 12, '12 some + 2,000 hourly readings, to be 30.10..... averaging 00.08 higher and apparently the Lg Mouth Bass have fully cooperated in not biting.
Being able to work with this data in Excel, has allowed me to plug into the hourly weather data, our very own Fishingreminder.com's Major and Minor times, and Luck being with me on this.... wouldn't you know that for every good time, (understanding it's winter) the barometer has been pretty much off the chart. Never the less..... INTERESTING....
I enclosed my local web address, located at Memphis International Airport, hopejully if you're interested you might find a weather center close to you, should you be interested in following historic trends....
