What do You see in this first image? Do You see a white mountain against a blue sky? Only one problem: we do not have white mountains in South Texas! So when I see something like this through the top of the trees as I am walking down the road, it can only mean one thing: that is one huge boiling cloud top on top of a giant cloud system. Let me introduce you to the Cumulonimbus Cloud in your infostudy. Then, we will ride out to the road where we can see this complete cloud system!
Come on in and put your head in the clouds!
Cumulonimbus capillatus incus
|Genus||Cumulonimbus (heap, cloud/severe rain)|
|Classification||Family D (Vertically developed)|
|Appearance||Very tall and large clouds|
|Precipitation cloud?||Yes, often intense, but may be virga (virga—occasionally a streak of precipitation but evaporates before it hits the ground)|
Part 2- Short slideshow of explosive break up of the Cloud System (drove out 5 minutes to side road).
Atmospheric thermodynamics is the study of heat to work transformations (and the reverse) in the earth’s atmospheric system in relation to weather or climate. Following the fundamental laws of classical thermodynamics, atmospheric thermodynamics studies such phenomena as properties of moist air, formation of clouds, atmospheric convection, boundary layer meteorology, and vertical stabilities in the atmosphere. Atmospheric thermodynamic diagramsare used as tools in the forecasting of storm development. Atmospheric thermodynamics forms a basis for cloud microphysics and convectionparameterizations in numerical weather models, and is used in many climate considerations, including convective-equilibrium climate models.
- 1751 Charles Le Roy recognized dew point temperature as point of saturation of air
- 1782 Jacques Charles made hydrogen balloon flight measuring temperature and pressure in Paris
- 1784 Concept of variation of temperature with height was suggested
- 1801-1803 John Dalton developed his laws of pressures of vapours
- 1804 Joseph Louis Gay-Lussac made balloon ascent to study weather
- 1805 Pierre Simon Laplace developed his law of pressure variation with height
- 1841 James Pollard Espy publishes paper on convection theory of cyclone energy
- 1889 Herman von Helmholtz and John William von Bezold used the concept of potential temperature, von Bezold used adiabatic lapse rate and pseudoadiabat

Part 3- The return home as a huge new cloud tower rises from the ashes of the last one!
Back home from the storm cloud chasing adventure. The cloud followed me!! (But NO RAIN for me)
