Re: Higher elevations equals more calm weather? Does elevation matter?

<mark@xxxxxxxxxxxxx> sayd the following:

Being I live on a hill in just this sort of scenario, here is what I
observe:

Storms tend to "split" as they approach my location from the west. One
half will remain over lower terrain, while the other will head up into
higher terrain. The storms tend to not linger where there is an long-
term elevation change. To my south it is an average elevation of 1500
ft and increases towards PA, to my north, 650 ft and slowly decreases
to lake Ontario. My house is situated on one of the first hills (1300
ft) as you approach Bristol hills from the north, so it is low-lands
and fairly flat to the north, high land and hilly to the south.

It is interesting to watch a storm make like a curve-ball and head out
over the higher terrain away from my location as my gardens wither.
Bristol mountain is the usual target for many of these storms, as it
is one of the highest elevations around at over 2200ft.

The nastiest storms are immediately to my north, which is partly due
to the deeper atmosphere providing more energy, and partly due to
convergence between lake Ontario, Lake Erie, and over land.

In all, even though I am at a higher location, we are in a transition
zone, and more often than not, the storms miss us. In fact it is quite
frustrating as I enjoy a good storm. When we do get a storm, we get a
little more lightning activity, but 600 feet of change from average
topology does not mean much to a 2-mile long lightning stroke.

So to answer your question: There are many more factors than two point
locations that need to be taken into account to predict a trend. In my
location the lakes provide the greater influence over storm paths than
the hills do. Down in PA where they are far enough away from lakes,
the hills have more influence (plus they are larger).


Well I was comparing two cities near me and their storm activity and
recorded severe weather events.

Johnson city TN compared to Chattanooga TN.

JC is about 1,000 ft above sea level Higher than chattanooga, and it
bears out in the noaa data that JC gets far fewer severe events than
chattanooga.

The same goes for the data on the appalachian mountain cities.

It seems the more of a plateau or mountain you're on the less chances
of severe weather.

We have a tiny mountain in town but you could drive your car around it
in less than 5 minutes, so the differences in weather are not extreme
except for winter weather like snow.


Of course their is the odd thing I love about last night. It never
stormed, not even lightening or thunder YET we had a 'severe
thunderstorm warming' because of 58+ mph wind gusts.

Kinda like a flood warning in the desert and it's not been raining.
Weird stuff.

One day I'll get over my fascination with weather but I suspect I
won't realize it since I'll be dead.


Anyone has anything else to add PLEASE do so.

I hate the politico posts just like you do.
