The absolute best desert windbreak tree is saltcedar aka tamarisk (it's also a good firewood producer) but it's messy and is considered invasive, tho frankly I've never seen it volunteer anywhere in the desert. It suckers thickly around the base which traps blowing sand. It will come back from any sort of abuse including being cut down to the ground every 3 years for firewood. (Yes, it grows that fast.) It's a small brushy tree with many sucker limbs when water-deprived, but I've also seen one growing right in a stream that got HUGE and looked like a regular tree. It will play dead during extreme heat, but comes right back. It is excellent quail habitat.
Eldarica pines (aka Afghan pines) are tough, twisty little trees that don't need much water and are heat and cold tolerant, tho they get much thicker if deep-watered about once a month during hot weather. (I'd just turn the hose on and let it run overnight 2-3 times per summer.) They grow much straighter and stronger if NOT braced when young, so don't give in to the temptation to tie them against the wind. They can stay thick around the base if not chewed by livestock. They can get bark beetles and host ground termites if repeatedly stressed or if there are injuries that expose the wood.
Italian Stone Pines are a tidy graceful tree of globular habit and fairly slow growth. They don't get bendy from the wind and are usually the very last to die under extreme drought. I never watered mine and it was the healthiest tree around. No pests that I ever saw.
There is a small-leaved form of Italian Cypress that does well in the desert, and tends to stay thick all the way down. I don't know the variety name but you will notice that the foliage is much finer and denser than average, and the tree's habit is narrower too (mine was still less than 3 feet wide at 35 feet tall). It is not affected by the wind and seems pretty flexible as to water requirements. No pests but will attract nesting birds.

Lovely tree, tough as nails, bees love it. It sits about 100 feet from the septic tank. It's roots completely filled that tank and the whole system had to be replaced.
