How can satellite images and other technologies used in information collection on the southern coast of the United States help predict the future arrival of the “La Niña” phenomenon?


Weather is an extremely important feature of our environment. It allows us to determine the consequences of human activity on Earth and is a vital aspect for every living being.

It is understood that the El Niño and La Niña phenomena are similar mainly because of the variables that affect them both, such as atmospheric pressure and ocean currents. However, their consequences to environment and society are different. In order to go further, we will focus particularly on the La Niña phenomenon.

La Niña is an atmospheric phenomenon that essentially generates a lower than usual temperature on ocean currents and produces an increase of precipitation rates. During the winter, large areas of the United States are affected, due to the lower temperature affecting crops, cattle, floods, and living conditions.

As a result, people need to be conscious of the dangers and effects that this particular phenomenon produces. Technology is a helpful tool.

However, technology and data still are not enough to accurately determine when the phenomenon might take place and how it might act that year. We must be aware of how taking care of our environment and natural resources can decrease the severity of the effects, and know how to act the next time a disaster occurs.
