### HAVE YOU BEEN THINKING ABOUT YOUR TROPOSPHERE LATELY? (WHAT REALLY HAPPENS THERE PHOTO BLOG)

Hi Everybody!!
I know some of You are thinking You did not know You had a Troposphere! Well, You do and it is very important to You. To help You upgrade yourself to some terms that have more importance in this information age than long ago when I was a kid, in your infostudy tonight, I bring an excerpt from Wikipedia on Troposphere to give you an idea of exactly where You are, where We All are! Your photostudy is some of the action happening in the Troposphere the last couple of days! (Storm Cloud Chasing!) I have been trying to rope a Rain Cloud and bring it home. Come In-Glide down the Post-and when You exit-You will know Troposphere. Snap, Presto-that easy!

Below is a Rain Cloud with Rain coming out the bottom of it!

# Troposphere

The troposphere is the lowest portion of Earth's atmosphere. It contains approximately 80% of the atmosphere's mass and 99% of its water vapour and aerosols.[2] The average depth of the troposphere is approximately 17 km (11 mi) in the middle latitudes. It is deeper in thetropics, up to 20 km (12 mi), and shallower near the polar regions, at 7 km (4.3 mi) in summer, and indistinct in winter. The lowest part of the troposphere, where friction with the Earth's surface influences air flow, is the planetary boundary layer. This layer is typically a few hundred metres to 2 km (1.2 mi) deep depending on the landform and time of day. The border between the troposphere and stratosphere, called the tropopause, is a temperature inversion.[3]
The word troposphere derives from the Greektropos for "change" reflecting the fact thatturbulent mixing plays an important role in the troposphere's structure and behaviour. Most of the phenomena we associate with day-to-day weather occur in the troposphere.[3]

Space Shuttle Endeavour appears to straddle the stratosphere andmesosphere in this photo. "The orange layer is the troposphere, where all of the weather and clouds which we typically watch and experience are generated and contained. This orange layer gives way to the whitish stratosphere and then into the mesosphere."[1]

## Pressure and temperature structure

### Composition

The chemical composition of the troposphere is essentially uniform, with the notable exception ofwater vapor. The source of water vapour is at the surface through the processes of evaporationand transpiration. Furthermore the temperature of the troposphere decreases with height, andsaturation vapor pressure decreases strongly as temperature drops, so the amount of water vapor that can exist in the atmosphere decreases strongly with height. Thus the proportion of water vapour is normally greatest near the surface and decreases with height.

### Pressure

The pressure of the atmosphere is maximum at sea level and decreases with higher altitude. This is because the atmosphere is very nearly in hydrostatic equilibrium, so that the pressure is equal to the weight of air above a given point. The change in pressure with height, therefore can be equated to the density with this hydrostatic equation:[4]
$\frac{dp}{dz} = -\rho g_n = - \frac {mpg}{RT}$
where:
Since temperature in principle also depends on altitude, one needs a second equation to determine the pressure as a function of height, as discussed in the next section.*

The slideshow below is from yesterday (8 3). Finally, a storm cloud system curious to the old granny storm chaser. (Go Granny Go)
Anyway, I chased this one over to Mitchell Road and tried to rope it and bring it home. All that got to my house was the top edge. No Rain, but great clouds! Enjoy!
