Let's solve each question based on the provided climographs and information. We'll analyze both graphs carefully.

1) The data used for the climograph of San Diego, CA was collected over how many years?
Answer:
The graph is labeled: *"Average Temperatures and Precipitation 1971–2000 (NCDC Data)"*.
This means the data spans from
1971 to 2000, inclusive.
To calculate the number of years:
- 2000 – 1971 + 1 =
30 years
✔ Answer: 30 years

2) Approximately how many inches of precipitation does San Diego get in January?
Look at the
San Diego climograph (left graph), find
January on the x-axis.
- The precipitation bar for January reaches about
2.2 inches.
✔ Answer: Approximately 2.2 inches

3) In which month would you be least likely to need an umbrella in San Diego?
An umbrella is needed when it rains. So we want the
driest month.
Looking at the San Diego graph:
- The lowest precipitation occurs in
July and
August, where precipitation is nearly zero.
- July shows
almost no bar — possibly less than 0.1 inch.
✔ Answer: July (or August, but July is slightly drier)

4) Approximately how many inches of precipitation fall in San Diego during an entire year?
Add up all monthly precipitation values from the San Diego graph:
| Month | Precipitation (inches) |
|--------|-------------------------|
| Jan | ~2.2 |
| Feb | ~2.2 |
| Mar | ~0.5 |
| Apr | ~0.1 |
| May | ~0.05 |
| Jun | ~0.05 |
| Jul | ~0.05 |
| Aug | ~0.05 |
| Sep | ~0.1 |
| Oct | ~0.5 |
| Nov | ~1.0 |
| Dec | ~1.5 |
Now add them:
- Jan + Feb = 2.2 + 2.2 = 4.4
- Mar = 0.5 → total = 4.9
- Apr = 0.1 → 5.0
- May = 0.05 → 5.05
- Jun = 0.05 → 5.1
- Jul = 0.05 → 5.15
- Aug = 0.05 → 5.2
- Sep = 0.1 → 5.3
- Oct = 0.5 → 5.8
- Nov = 1.0 → 6.8
- Dec = 1.5 →
8.3 inches
✔ Answer: Approximately 8.3 inches per year

5) Which month has the highest average temperature in the "mystery city"?
The "mystery city" is the one on the
right-hand climograph, with:
- Elevation: 597 ft
- Latitude: 41°52'N
- Longitude: 87°37'W
This location is near
Chicago, IL (but not exactly — this is a fictional or representative city).
Look at the
temperature line (red dots) in the right graph.
Find the
highest point on the red line:
- It peaks in
July.
✔ Answer: July

✔ Final Answers:
1)
30 years
2)
Approximately 2.2 inches
3)
July
4)
Approximately 8.3 inches
5)
July
