How Does El Nino Affect Global Weather

You may have already heard on the nightly news that the scientific community is concerned about El Nino conditions this year, but many do not even know what El Nino really is. Many weather terms are tossed around on a regular basis with little understanding of what the occurrence really is. This article is designed to help you understand El Nino and find out what preparations need to be done if any.


An El Nino is the warming of the surface waters in the centrally located Pacific Ocean. While the warming of waters may not seem to be that drastic it creates the possibility of drastic weather systems across the globe.

North-easterly winds push warmer waters westwards through the Pacific Ocean onto Indonesia, letting cool water rise to the surface further east off the coast toward Mexico and South America.

As these north-easterly winds weaken an El Nino will begin to develop, this allows warm water over the west Pacific to move eastward into the Americas.

If trade winds were to strengthen a La Nina would develop and the waters would become much cooler.

An El Nino’s effects are rather easy to track and predict around the Pacific Ocean. During these periods of instability, South American and the south-west United States will see much higher amounts of rainfall. For areas such as California who have been involved in a drought for several years that is welcome news.

With warmer waters though comes the risk of more hurricanes. Two hurricanes have already developed off the west coast of Mexico and more can be expected. During this time period hurricanes in the Atlantic area tend to become lower.

In other parts of the world, it has yet to be determined what exactly are the affects of El Nino if any. It may depend on the time of year and how much the water warms. In fact, in Europe and the UK it has been impossible to determine any significant changes at all.

When there is a particularly strong El Nino, there is an increase in high pressure across Europe that leads to warmer and drier weather. El Nino is only beginning to develop and is unlikely to be particularly strong, it is not expected to have much impact on European weather.

One of the last strong El Ninos occurred in 1997/98 when the centrally east Pacific water temperature rose an incredible 4C. That ended up being one of the warmest global years on record. There have been no major El Ninos which may be one of the reasons we have seen very little global temperature change in the last 15 years.

Best Weather to Grow and Obtain Quality Green Coffee Beans

Coffee beans have quite the market around the world, but there is an art to growing them for those who want to control the process. There are specific parts of the world with certain climates in place that are going to be able to yield quality coffee beans. Other options are just not going to cut it and that is why only a select few around the world are able to grow them in the first place. Let’s take a look at what the best weather is to grow high-quality coffee beans. This topic was contributed by GCB Max website.

Height Requirement First

Regardless of the weather, there is one thing that has to be consistent and that is the height at which these coffee beans are going to be grown. This is certainly the case for arabica beans. They are going to need at least 1000-3000 feet height to ensure the growth is as required.

This is why most are grown in the hilly parts of the land to ensure maximum value is being produced and the coffee beans are as good as they should be. There is truly a science behind how things are done for the beans to grow.


Subtropical Regions

These regions are great because of how their weather works. There are distinct periods where the weather changes from rain to sunny on a regular basis. This is the only way to make sure the results are up to par. Those who don’t think about this are the ones who are going to lose out the most.

The reason for these changes is because coffee beans are going to have a maturation requirement where the weather has to be cooler. This will ensure the coffee beans are able to sustain their quality. Add this along with the height requirement of at least 1000-3000 feet and the best places are Brazil, Mexico, and Zimbabwe in these regions.

Equatorial Regions

Another option that tends to do the trick for those who are going to be growing coffee beans would come in the form of equatorial regions. These are locations which are higher up as required for the height, but also are going to have frequent rainfall. This is going to allow for the maturation process to kick in like the subtropical regions.

The best examples of this region would include places such as Columbia, Kenya, and Ethiopia to name a few.

This is what is required to grow great green coffee beans and those who are able to house farms in these locations are going to get fantastic results. In the end, any place where there are specific seasons where it rains a lot and is sunny on a regular basis with warmer temperatures will get the best results. Places, where it snows, are just not going to be able to grow coffee beans at all. It is not going to work out. This is despite those nations being the ones who require coffee the most at the end of the day!
