The old weather Wiz

Tuesday, June 2, 2015


This week I would like to venture into a situation that can be very costly both in property and loss of life.   Let’s examine the tornado.  This is usually a rather small storm, but extremely violent. Tornadoes generally affect an area only, perhaps, a mile wide.  However, it can move along the earth for many miles, affecting all those located in its path.  Tornadoes usually develop from severe thunderstorms. Generally, the scenario goes like this.  Hot and humid air exists in the Gulf States.  Cold air comes racing south from Canada.  Meanwhile, dry air is filtering into the area from the west, coming down slope from the Rocky Mountains.  The mixture of hot moist air with cold dry air plus in infusion of air from the west makes the atmosphere extremely unstable.  First, the severe thunderstorm, then the spinning funnel appears.  Some funnels never touch the ground, others do. Much study is being devoted to the dreaded tornado.  Great advances have been made, but still much is unknown.

Now during the month of February tornadoes begin affecting the states bordering the Gulf of Mexico.  As March and April approach, tornadoes begin to develop in the Texas, Oklahoma, Nebraska area and surrounding states.  Come the months of May and June, it is common to see tornadoes ripping across the landscapes of Iowa, Missouri, and Minnesota, even the Dakotas.  It is safe to say, however, very few places in the United States never experience a tornado. 

During the spring and summer, it is not out of the question that a tornado touches down in the northeast.  Unlike the tornadoes in the Gulf States and the mid west (tornado alley), tornadoes in the northeast are usually of very short duration.  Some funnels just skim the ground, other remain on the ground only for a few minutes.  Tornadoes out west, where the ground is flat, can stay alive for an hour or more, causing devastation everywhere in its path.  Some tornadoes travel for hundreds of miles, knocking down huge trees, telephone poles, wires, throwing cars and trucks around like they were toys, even flattening buildings. Many people living in areas that are prone to tornadoes construct storm cellars in order to survive.

Stories about tornadoes are quite common. Unfortunately, many of them are true.  We hear about a baby being ripped from a mother’s arms and found a few blocks away with only a few scratches and bruises.  We hear of cars and huge trucks being carried high in the sky and being whirled around in the funnel, finally coming back down to earth as the tornado weakens.  One man went into his storm cellar and his dog was following.  As the tornado went overhead, the dog was sucked out of the cellar into the tornado.  The dog was never seen again.

So what should you do if a tornado is heading for your area and you do not have a storm cellar?  Cars are not safe.  Holding on to a tree is no solution.  The best thing one can do is finding a structure.  If you are close to home, get into your house.  If you have a cellar, go down into the cellar and stay away from windows.  If your house has no cellar, and many do not, get to the center of the house …again, away from windows. If you can, get on the floor, perhaps under a bed.  Some have suggested get into the bathtub and if possible cover yourself with something to protect yourself from falling objects. Do not, I repeat, do not go outside to take pictures of the tornado.  Many a life has been lost doing that.

Next week I will discuss another killer storm, the dreaded hurricane. When does it occur? Where does it occur? And how does it usually kill.

Spring Rain


Spring is here and for the eastern half of the country it has been some winter.  Very cold into the deep south and plenty of snow up north.  The sun is now advancing slowly northward and hot weather will be upon us. Hello to another weather phenomenon, the thunderstorm.  We are all familiar with thunderstorms, heavy rain, gusty winds, lightning, thunder and even sometimes hail.  Let’s take a closer look at a thunderstorm and see what causes it. 

Basically you need heat, cold and moisture.  Specifically, very warm or hot air at the surface, plenty of moisture available and a very important ingredient cold air in the upper atmosphere.  When it is hot at the surface and cold aloft, we say the atmosphere is unstable.  So, here We go…on a hot summer afternoon, surface temperature readings in the 90’s, the surface air is very moist, the air begins to rise.  As long as this Parcel of air is warmer than the air surrounding it, the air will continue to rise.  As this air rises higher in the sky, the upper air surrounding the parcel continues to be colder and colder.  This causes the air to continue to rise.

 The air will rise until the air surrounding this parcel is the same temperature as the parcel.  If, however, the upper atmosphere is cold all the way up to 60,000-70,000 ft. The parcel will rise that high.  Also, remember the surface air contained a great deal of moisture.  Well, air is like a sponge, warm air can hold a large amount of moisture, however, as the air gets colder, it is like squeezing the Sponge.  Water is released,  if you squeeze the sponge quickly, a great deal of water is released at once….a Heavy downpour.  So, in general, rising air causes clouds and precipitation because rising air expands and cools  and can not hold as much moisture as warm air can. That explains the rainfall during a thunderstorm…what about the lightning and thunder?  Let’s forget mathematics etc and explain these features in a very down to earth fashion.   In a thunderhead cloud, also called a cumulonimbus cloud, there is plenty of water vapor.  Water, as you know, is h20

Two hydrogen atoms and one oxygen atom.  Hydrogen has an electrical charge of plus one.  Since there are two hydrogen atoms, it has a plus two Charge.  However, oxygen has a negative charge, a minus 2 charge.  So, when you combine two hydrogen (+2) with one oxygen (-2), you get water.

With a zero charge.  In a thunderhead cloud there are tremendous up and down drafts of air.  Planes flying through a thunderhead would be damaged severely if not destroyed completely.  Anyway, these up and down drafts of air rip the water molecules apart.  The h’s are ripped from the (oh’s).  These particles are now charged.  The (oh) has a negative charge while the “h” has a positive charge.  The positive charges accumulate at the top of the cloud while the negative charges are found at the base of the cloud.  Beneath the cloud, positive charges prevail.  Since opposites attract, the positive and negatives try to interact.  As the storm system moves along, the positive charges on the ground follow along.  Finally, when A high object appears in the storm’s    path, the positive charges climb up the high object, be it a tree, a hill, a tall building.   The negative charge and the positive charge are now closer together and there is less resistance between them. 
A huge spark occurs when the charges comes together.  We call this lightning.  Lightning can go from cloud to ground, we call this cloud to ground lightning.  Sometimes lightning goes from one cloud to another cloud and does not strike the ground.  We call this cloud to cloud lightning.  Next week i will talk more about lightning , a few safety measures and then discuss thunder and hail.
