5.     a double bar graph showing average relative humidity per week 

6.     a double line graph comparing NH city high temps to SH city high temps

7.     a double line graph comparing NH city low temps to SH city low temps 

8. A line graph showing AVERAGE Monthly precipitation for 30 months

You must generate 1 additional computer graph of your choice. 

and possible explanations for what is observed.  Remember, each graph must have labels, units, title, intervals marked, and a data table. 

Paragraph Rationales: Paragraphs will need to include appropriate vocabulary properly used in explanations.In the first paragraph, you must 

explain

·         the variables that govern the local weather such as geography

·         the types of air masses that originate over the area; 

·         the generalized climate for the area

·         the wind belts and ocean currents contributing to the weather

·         Analysis of the 30 day weather-is the weather observed typical of the area and how do you know?

·         Be sure that you refer to your graphs in your writings 

In the 2nd paragraph, you must explain
Using comparative language, describe how weather changes throughout the year in both cities.
How is climate projected to change over the next 50 -100 years
How will climate changes affect the local weather patterns,  if at all

Recording the past is always easier than predicting the future. When it comes to weather forecasting, an understanding of the mechanics of weather, access to information about past weather events, and a knowledge of the region all contribute to increase the accuracy of predicting tomorrow's weather. Below, you will find some helpful definitions and websites to use for your mapping lab.
Today, you are completing Part II of your weather Project.  Some of you do not have all your maps and summaries. There will be a penalty deduction for this negligence on your part.  You have known about this assignment since January 25th.  
Directions:  You need to obtain the following:
Blank Maps of the US
Analysis Questions and Conclusions
Computer to share
Colored pencils
A Set of Maps: Either March 1-5  or March 8-10
In addition: you should go to the sites below and observe how the newspaper maps you have were developed and the amount of data that it took to make them.  You are to go to each site and glean any information you can to help you answer your questions and make your summaries beyond descriptions.  You should be focusing on the relationships of the weather variable with one another--not just telling about the pictures.  Think: Compare: Contrast: Sequencing: Cause and Effect----yes thinking maps.  Incorporating a Multi-flow map or double bubble, or Flow Map will get you extra credit in your final summary.   *Do not freak---this part is to be turned in on Tuesday, March 16.

Make a list of words you find in the discussions that you are not familiar with like the two listed below.  You will need to know these 

words for Part III when you observe the meteorlogists.  Many of the sites listed below give definitions. Also, do not forget about WW2010-

lots of good information and explanations of meteorological phenomenon.  

Trough An elongated area of relatively low atmospheric pressure, usually not associated with a closed circulation, and thus 

used to distinguish from a closed low. The opposite of ridge.

Ridge   An elongated area of relatively high atmospheric pressure; the opposite of trough.

7 KEY FORECAST VARIABLES

Wind Direction:

          Wind is always reported as where it is coming from.

          A north wind means from the north and therefore most likely cooler temps.

          A south wind means from the south and therefore most likely warmer temps.

Cloud Cover:

Clouds prevent incoming sunlight while preventing outgoing radiation overnight.

When all other factors are considered:

          Clouds during the day cause cooler afternoon temps.

          Clouds overnight cause warmer morning temps.

Wind Speed:

          Wind has a moderating effect on temps.  Assuming no major air mass changes (no 

fronts) and when considering all other factors:

                   Windy nights are warmer and windy days are cooler.

                   Calm nights are cooler and calm days are warmer.

Thickness:

          Thickness values relate to air density which is primarily due to the average air 

temperature in the lower troposphere.

        Higher thickness indicate a warmer lower atmosphere.

          Lower thickness indicate a cooler lower atmosphere.

850 mb T:

Temperature of the air near 5,000 ft. above sea level.  Rapidly changing values 

indicate an air mass change, and most likely a frontal passage.

Dewpoint T:

          Air temperature cannot drop below the dewpoint value.  Therefore, dewpoints help 

to forecast the lowest possible temperature overnight.  Dewpoints do NOT 

influence daily high temps.

Air Pressure:

          Air pressure changes can signify the passage of weather systems, including

weather fronts.  Typically, pressure falls fairly rapidly before the arrival of a cold 

or warm front.  After a cold frontal passage, pressure normally rises rapidly due to 

an increase in air density.  After a warm frontal passage, air pressure may remain 

constant or fall even lower due to a lower air density.
