Planet Twylo

Chapter Three: The Climate of Twylo

Our planet Twylo is a fairly cool planet as compared to Earth. The average temperature of Twylo is 10.71 C as compared to 25 C on Earth. The planet has 76.63% water and 23.37% land mass and only 2.7% ice at the poles. This is important in that is has a strong effect in determining such things as weather patterns, air currents and water currents.

The rotation of planet Twylo is counterclockwise, which is the same as Earth's, therefore all of the weather systems travel from west to east. In the areas of heavy rainfall it generally rains more than two hundred inches per year. These are the dark green areas and they generally are tropical in nature with a lot of growth and vegetation. These areas would be considered rain forests. The areas of moderate rainfall are areas where it rains from about one hundred to two hundred inches per year. These areas are associated with areas that have a lot of trees, large forests, but not as abundant as a tropical rain forest. Also found in these areas are large bogs and swamps. The next area is the area of light rainfall which would have twenty five to one hundred inches of rain per year. This would be characterized by small bushes and large grasslands. Also, one could find savannas in these areas. The final area is the dry area which would have from zero to twenty five inches of rain per Twylo year. These areas would be characterized as deserts.

Due to the distance of Twylo from our sun, Sulfina, Twylo has an average temperature slightly less than Earth's. Its average temperature is 10.41 C. The temperature in zone 1 near the equator is about 25 C and gets cooler as you move either north or south from the equator. The temperature in the zone 2 averages about 10 C and finally, at the poles, the temperature averages about -2 C. These zones support various life forms depending on their adaptability to the temperature. Fig. 2 is a relief map showing the temperature of Twylo.

The planet has a rotational rate of 14.3 hours as compared to 24 hours on earth and is has a diameter of 14,774 km which is about 2000 km greater than the Earth. Due to the high rotational rate and the fact that it is only slightly larger, the air currents move very rapidly. There is a very large jet stream in the northern hemisphere and occasionally it will change its course which will drastically change the weather just north of the equator. There is smaller jet stream in the southern hemisphere and this has a similar but smaller effect than the northern one. On the equator there is there is very little wind and this wind is generally warm due to the fact that it is on the equator and when this warm wind interacts with the jet stream, we get heavy rainfall and strong storms. Fig. 3 is map showing the air currents on Twylo.

Due to the fact that Twylo only has three continents, the ocean currents are fairly simple. There are basically two major ocean currents that move from west to east around the continent Equat which is situated on the equator. These ocean currents are warmer than the surrounding ocean and mimic a Gulf Stream type current on Earth. These currents help to provide warm water to northern latitudes and to southern latitudes and due to up welling of currents, they help to provide nutrients for an abundance of sea life in the higher and lower latitude regions. Fig. 4 is a map showing the ocean currents on Twylo.
