"If it has already rained, it's going to continue to pour," according to a Purdue University study of how ocean-origin storms behave when they come ashore.I love the above quote. While they are clearly talking about Tropical Storms originating off shore over open sea where they gain their strength, energy and momentum, once they come ashore their intensity and longevity are determined by the moisture content of the soil on landscape over which they move.
"Once a storm comes overland, it was unclear whether it would stall, accelerate or fizzle out," said Dev Niyogi, Indiana state climatologist and associate professor of agronomy and earth and atmospheric sciences. "We found that whether a storm becomes more intense or causes heavy rains could depend on the land conditions - something we'd not considered. Thus far we've looked at these storms based mainly on ocean conditions or upper atmosphere."What was fascinating about watching the buildup at certain specific locations during those drier periods, was that the same locations would always be first to kick off the monsoonal development. The main cloud formation starting points for which the leading tip of the cloud flank would actually manufacture separate cells, one after another with the first, second, third and so first over multiple times at 10 minute intervals. Most first development often started over the Buck Snort Mountains south of Terwilliger which had heavy dense undeveloped Redshank dominated chaparral forest on the southern region of Cahuilla Reservation. What was interesting about this location which always seemed to receive the regions first downpours was that the first rains would start there and over a period of days into weeks while the pattern existed, would widen out and expand beyond the chaparral over to the drier grassland regions of Terwilliger. But always the initial main downpour always remained mostly over that old growth chaparral location. As the expansion grew, so did storm intensity where larger portions of moist ground conductivity increased more extensively. It's exactly as described in the quotes below.
"The same phenomenon - the evaporation from the ocean that sustains the storms - could be the same phenomenon that sustains that storm over land with moisture in the soil," he said. "The storm will have more moisture and energy available over wet soil than dry."

This photograph I'm using as an illustration of what I use to see over the Salton Sea at around 4:00 - 5:00 in the morning, the day after Thunderstorms had come and gone over the mountains east and west of Imperial Valley. While storms often never rumbled over the sea during the day, At night was always a different story. While the mountains were often cooled down and uplift not as great, the deserts at night were always different, with loads of uplift energy. Towards morning however, even the deserts would quiet down. However, energy was always over the Salton Sea. The sea often times could have four or even five small isolated Thunderstorms. The eastern sky horizon on the eastern side of the sea towards Arizona was always a blaze before the sun came up. The mushroom shaped storm clouds themselves were mostly black silhouettes and even the rain bands themselves were mere streaks flowing from cloud to water. The only real colour other than the beautiful sunrise would be the intermittent flash of lightning hitting the sea below. I never had a camera with me when I'd see such scenes. I was always in a hurry to get to Brawley or El Centro CA. One day someone with a mind to will document such breath taking scenic natural phenomena over a body of water mostly demonized for something not it's fault and over which it has no control over. Still, this beautiful Sea and those storms prove the worth of the research provided by researchers on the important conductivity of heavy moisture to sky thunderstorm formation.

So then, this description I've given about Anza and Terwilliger Valleys is also identical to this next article later in 2011 where cloud formation over a combined mosaic pattern of dry and wet landscape helps storm development in the sub-Sahara called the Sahel Desert regions. In the above picture with the Storm over the desert, it reminds me of storm creation over chaparral which then proceeds to move over the drier grassland of Terwilliger. Of course this is an entirely different circumstance, but the components are almost identical. Why more research, habitat design and rehabilitation establishment never has these climate developments in mind as a goal is beyond me. These stuff never gets explained to anyone. You'll never find it in textbooks. This information also illustrates why remote heavy vegetation growth [Chaparral Plant Community in southwest regions] far far away from any Human development should never be deliberately prescribed or control burned. Rouse Ridge from Thomas Mountain to Cranston Ranger Station on Hwy 74 comes to mind. When I was living in this area in the 80s & 90s, that ridge was continually under fuel management programs. Never have I ever seen or heard of major fire starting there and moving towards civilization to the west which is what they have always feared. All they have done is allow non-native weeds and grasses to invade and almost guarantee a disaster scenario. But most all mountains with inaccessible terrain should always be maintained & kept as an old growth biological weather creation and moderating mechanism if they really believe or want to reverse this climate change. Global obliteration of many of these ecosystems has contributed heavily to weather pattern disruption. The CO2 increases, warming Temps and other factors are mere symptoms of the real problem. But not one viable recommendation of vegetation rebuilding can be found anywhere from any Nation. Mostly the stupid solutions being promoted are of an artificial nature because it involves someone making a profit off the deal. Some things should not be pursued just because there may be financial gain in it for some corporation, but because it's the right thing to do.

I'm making this post as a source of reference for my posts on what Juan Baustista de Anza wrote in his diary with the description of the richer plant and animal landscape he saw first hand and documented in text. At one time I had thought his work was an exaggeration, but clearly it was not. I also want to counter some of the myths of larger and greater forests of the region being in existence 1000s of years ago, when it is clear that the existence was even around in many areas just a few hundred years back. It may take thousands of years to create and build, but it takes a mere 150 years to wrecking ball it.
I also appreciate that much of this may be boring to most people, but knowing the natural mechanisms can actually help in rebuilding the Earth. Of course that's assuming that every individual on Earth actually cares and get's the implications of not caring. The one thing Science is incapable of doing is changing people hearts which motivates behavior. Scientists haven't exactly been the best of communicators historically, but that will have to change. Expecting such a thing to happen of course is like saying the world's leadership from Politicians to Religious Clergy will change for the better. Hmmm, "When the Sahara Freezes Over" - even still, practical application of things observed out in nature can still benefit people on an individual level.
(Note: Don't kid yourself that all this understanding is new and fresh. The Scientific authorities have known about these natural mechanisms for years and have done nothing to make practical application in replication of the observation.)
