When it comes to meso and micro scale features that affect the climate of Dublin Ireland, the Liffey River and Dublin harbor are really the only ones.  The Liffey River can affect Dublin because it can flood when there is excess precipitation.  Dublin Harbor can affect the climate by gathering water from the North Atlantic Current and keeps the water warmer by having it stay in the harbor.

TABLE   Graphs. These each are by 10 years from when the data began in 1881 to when it ended in 2009.  Y axis= degrees Fahrenheit  X axis= years 1- 1881 2- 1890  3- 1900  4- 1910  5-1920  6-1930  7-1940   8- 1950  9- 1960  10- 1970  11- 1980  12- 1990 13- 2000  14-2009

Everything seems to be in direct correlation except for a small spike in 1990 in the average high temperature.   The average temperature for both may have risen slightly since 1881.

Everything in January seems to be in direct correlation in the highs and lows in January but the average low in July does not spike as much as the high does in 1990.  The average temperature for both may have risen slightly since 1881.

I chose to compare Dublin Ireland to that of Surrey, England.  In general it is a very similar location and a very similar climate.  The average annual temperature of Dublin is lower by 6 to 7 degrees on the high end. The winter low in both Surrey and Dublin are about the same.  Dublin gets a little bit more rain but both locations get most rain in the winter months and the least in the summer months.  Everything else seems to be very similar and have little to no differences in any other major climate categories.

More Weather and Climate of Dublin, Ireland. (Blog #2)

Eric Blayney

Ireland climate as I discussed in my previous blog is generally stable and does not experience much weather outside of fog and rain. When it comes to severe weather such as hurricanes and tornadoes, there are none.  The only severe weather that can happen although rare is flood from rains.  There cannot be flash floods because there is no big mountain range affecting the climate.  As I also discussed in my previous blog, the North Sea is really the only thing that affects Dublin’s climate. So other than the ocean, nothing else really affects the weather and Climate of Dublin. 

When it comes to air masses in Dublin, it is affected by both cT (continental tropical), and mT (maritime tropical) in the summer seasons.  In the winter seasons it is affected by both mP (maritime polar), and cP (continental polar).

This weather map is for Friday November, 16^th. As you can see there is a cold front heading on its way over Ireland. There is also a warm front coming in from the south that’s off the coast of France and Spain.  The two fronts may collide into a stationary front. There are occluded fronts in Iceland and off the coast of Portugal.  The occluded front in Iceland may not come to Ireland because it will probably separate or move in a different direction off the low pressure that is where Iceland is.  The occluded front off the coast of Portugal may come up from there but will probably miss Ireland to the East. The occluded front in Iceland is probably a cold occluded front, and the one in the ocean off the coast of Portugal is probably a warm occluded front.

Monthly Climate of Dublin, Ireland

I chose to do my report on a weather station in Dublin, Leinster, Ireland which is on the Eastern side of the island on the coast of the North Sea. Ireland is not very mountainous and is very consistent across the country, whether inland or on the coast. Being on the coast gives Dublin a maritime climate which means there is more moisture in the air and the high and low daily and annual temperature range are consistently closer together. This is because of the Gulf Stream carrying moisture into the North Atlantic which gives Dublin its mild climate. There is little to no extreme weather in Dublin as a result to its rather stable atmospheric conditions. The Bowen Ratio of Dublin would be like that of a maritime climate.  This means the ratio is going to be lower than most inland cities. My estimate for Dublin’s Bowen Ratio would be about 0.50.

 I found this weather station at http://gis.ncdc.noaa.gov/map/viewer/#cfg=cdo&theme=monthly&layers=1&node=gis

 

This is a graph that shows the average monthly temperature of Dublin.  July and August have the warmest average temperatures and January and February have the coldest average temperature. This is expected because of the fact it’s in the Northern Hemisphere. This shows how little change there is in seasons because of its maritime climate.

This is a graph that displays the average monthly precipitation of Dublin, Ireland. The autumn and early winter months have the most precipitation. Most of the precipitation comes in the form of rainfall.
