Temperature Controls in the city of San Salvador in El Salvador

Temperature controls are different reasons why the climate of an area is the way it is.  The main temperature controls are differential heating, ocean currents, altitude, geographic location, and cloud cover and albedo.  Looking at the different ways temperature is affected there are certain controls that have a definite impact on El Salvador's climate and culture.  We will be specifically looking at the capital city of El Salvador.

The capital of El Salvador is San Salvador and has a latitude of  13° 42' North and a longitude of 89° 12' West (World Clock). San Salvador generally has a warm tropical climate but the temperature varies.  The warmest month is April with an average monthly temperature 76.1 degrees.  The coldest month is December with an average monthly temperature of 71.6 degrees.  The annual range of temperature is about 73.9 degrees (World Weather).  

One of the main temperature controls of San Salvador is ocean currents.  El Salvador is on the coast of Central America and therefore the ocean plays a big role in its climate.  Warm water comes up from the equator and gives the country its warm tropical climate.  If there weren't ocean currents the climate of San Salvador would be cooler.

On the other hand, altitude does not have too much affect on climate.  San Salvador elevation is 2,238 ft.  This is about the elevation of Eagle Mountain in Minnesota.  When there is a increase in altitude there is a decrease in temperature because of a decrease in pressure.  Although this is true there is not a big change in temperature and San Salvador has close to the same temperature as other places in El Salvador.  San Salvador does experience more rainfall because of the elevation.

Climate change is a major topic right now.  There are many things that cause climate change such as natural disasters.  In El Salvador hurricanes, earthquakes, droughts, and volcano eruptions effect the climate.  In 2008 and 2009 El Salvador experienced droughts followed by flooding in 2010 and 2011 (weadapt.org).  Since the ocean is getting warmer and ice caps are melting it is causing the sea level to rise which can be a big problem with flooding for this coastal country.  Climate change has actually been a very serious topic in El Salvador over the past few years and the government is coming up with different solutions to help with their problems.  The main problems are with farming conditions and the need for fresh water.

El Salvador depends on its climate for its farming industry.  Knowing what temperature controls affect its climate and how they may change it is very important.  In El Salvador's case, it is very important to know the changing climates to be able to determine how their farming industry and just people's lives in general will be affected.

  1. San Salvador's climate is very interesting. I am researching the climate of Harare, Zimbabwe in Sub-Saharan Africa. The climates and temperature controls of San Salvador and Harare seem like polar opposites. San Salvador is hottest during April and coldest during December, and Harare is hottest during November thru January and coldest in July. Both cities exhibit wet and dry seasons, but again, the seasons are exactly the opposite. San Salvador accumulates much more rainfall then Harare, but exhibits slightly less seasonality with an annual temperature range of 7.2 degrees fahrenheit as compared to Harare's 14 degrees.
