Answer:
There are a number of factors that could contribute to more rainfall on the west Ferris side of an island compared to the east Ferris side. Some possible factors include:
Orographic lifting: If the prevailing winds blow from the east to the west, they will encounter mountains or other high terrain on the west side of the island. As the air is forced to rise over the mountains, it cools and moisture in the air condenses, leading to precipitation.
Distance from the equator: If the island is located closer to the equator on the west side than on the east side, it is likely to receive more direct sunlight and thus more heat, which can lead to more evaporation and precipitation.
Prevailing winds: Depending on the direction of the prevailing winds, the west side of the island may be exposed to more moisture-laden air masses, which could result in more rainfall.
Temperature gradients: If there is a significant temperature gradient between the east and west sides of the island, this could create differences in air pressure that result in more precipitation on one side than the other.
Topography: The topography of the island itself could play a role in rainfall patterns, with valleys or other low-lying areas on the west side acting as catchments for precipitation.
Ocean currents: Depending on the location of the island, ocean currents could also influence rainfall patterns, with warmer currents leading to more evaporation and thus more precipitation.
