In each references is: ""Wordwide thunderstorm activity is responsible for

maintaining a weak
 negative charge on the Earth's surface and a corresponding positive 
charge 
in the atmosphere."

We are discussing about the "positive  charge in the atmosphere."
Do you neglect "a weak  negative charge on the Earth's surface".

Here is sci.physics.electromag. Here is enough: "Wordwide thunderstorm 
activity is responsible for maintaining a weak
negative charge on the Earth's surface and a corresponding positive 
charge 
in the atmosphere." That sentence is from meteorologist area. My intention

is to inform physicists that the "positive  charge in the atmosphere" in
the 
above sentence means that electrons migrate up at fair weather  and in the

result in the air is an excess of electrons. It is im****tant at
determining 
the force direction for winds in the Earh magnetic field.
