Maucabrei

A desert world that has painfully high temperatures, along with hurricanes and typhoons that reach the stratosphere and create tornadoes made of CO2.

## General

Maucabrei is one of the Desert planets orbiting a binary star system consisting of a White Giant and Yellow Dwarf, found in the galaxy **Sextans dSph**. The planet appears to be around 771 million years old, making it relatively young.

## Atmosphere

The atmosphere of the planet is extremely toxic, mainly consisting of CO2. This CO2 is also likely what contributes to the planets rather high temperature. However, due to the atmosphere being thinner than the one found on Earth, the greenhouse effects haven't transformed the planet into a full-blown Venus world.

### Weather Patterns

The weather on Maucabrei is surprisingly varied, with scorching heat waves and giant hurricanes swamping the planet. On an average day, the daytime sky will only have a few clouds of the "Cirrus" genus, which is a type of cloud only found in the upper troposphere and which is mainly made up of ice particles. However, on Maucabrei, the cirrus clouds are made up entirely of vapor due to the temperatures on the planet.

Heat waves on the planet are not rare, mainly happening in the summer season. When they do strike, they can cause large areas of the planets surface to stagnate, stopping any and all erosion due to the complete and utter absence of wind.

On the other hand, large hurricanes and storms are also pretty common on the surface. They are mostly formed around the poles, where temperatures and conditions are just right enough that storms can form. From there, these storms are carried by the wind, and along the way, either dry up and disappear or get even bigger and turn into cyclones. The weather in these hurricanes is devastating, and wind speeds can go up to 350km/h. The clouds are mainly formed out of CO2, and the rain, while not very strong, is extremely acidic due to being made out of CO2, Sulfur molecules and various other toxic materials. If conditions are just right, entire tornadoes can form, which, while powerful, are surprisingly not as strong as those found on Earth. In fact, the strongest tornado recorded on Maucabrei was only an EF3, compared to Earths EF5 (or possibly even EF6).

Lightning is also quite common in these storms, and some are even strong enough to cause Sprites to form in the upper atmosphere. (For reference, Sprites are large-scale electric discharges that occur high above thunderstorm clouds. They are found on Earth, where they have a distinct red color due to being made up of ionized Nitrogen, along with likely appearing on gas giants and possibly even Venus. However, on Maucabrei, these sprites are a very light gray color due to being mainly made up of ionized CO2)

After a timespan of either a few weeks to several years, these hurricanes gradually shrink and eventually disappear. The cycle then repeats over and over again.

## The Maucabrian Great Canyons

The Maucabrian Great Canyons, also known as the Northern Maucabrian Canyon and the Equatorial Maucabrian Canyon, are gigantic canyons found on the Northern pole and Equator, respectively. The larger of the 2 canyons is the Northern, but that doesn't mean the Equatorial one is small. Both canyons are absolutely humongous, and are quite similiar to Valles Marineris, the canyon found on Mars. These 2 canyons were formed as the planet cooled, and were made bigger by the rising of the planets crust along with erosion. They are the planets biggest land features.
