In other countries, weather conditions can easily be determined. However, in the US, it may be a difficult task. The reason for this is mainly the US is a big country and it is divided into a lot and different regions. There may be some things that are similar with different areas. For example, areas in the upper part of the country is likely to have a cold and wet climate, while the lower part cooler but still comfortable. Generally, this can be said however, due to the different phenomena happening in our world, it is difficult to determine what the weather is going to be like.
There are already a lot of natural disasters that may affect the long term weather forecast in the US. One would be the recent volcano activity around the world. The very strong and destructive earthquake that hit Japan this year also affects the global weather. Also, the earthquake in Indonesia a few years ago has changed the rotation of the earth slightly. These tragedies may be small but it can bring large amounts of impact to the world and may be factors to change in weather on the long run.
Consider when a volcano eruption occurs. During an eruption, a volcano releases a huge amount of hot, molten lava and spurts ashes into the air. Those ashes are not gone in just one day. While they exist, they can affect clouds and cloud formation, possibly increasing or decreasing the amount of precipitation that the cloud can give off. Even disasters that are not natural may still have an effect on the environment. Nuclear power plants that may have been leaking or blown up may cause disastrous changes to the environment.
There are resources that one can use in order to predict long term weather conditions. The Farmer’s Almanac contains documents and reports regarding long range weather forecast. The book has seven sections, with forecasts as far as the month October. This is the most that a weather forecast can cover. By the start of the winter, a new period of forecasting will take place.
