Question
Animal temperature range for a place is calculated by the formula: warmest month on average - coldest month on average (For Fresno, the range would be 36 degrees F: 82 F in July - 46 F in January.) Consider the annual temperature range data for the two cities below: Portland, OR: 28 degrees F Minneapolis, MN: 62 degrees F Since both cities above are located at the same latitude, 45 degrees North, they both possess essentially the same day lengths and sun angles throughout the year. However, why do Portland and Minneapolis have such different annual temperature ranges? Discuss in detail.Explanation / Answer
Portland and Minneapolis have such different annual temperature range because
- Portland Oregon has a Mediterranean warm climate (Csb) whereas Minneapolis, Minnesota has a hot summer continental climate with no dry season (Dfa)
- Portland, Oregon is in or near the warm temperate moist forest biome whereas Minneapolis, Minnesota is in or near the cool temperate moist forest biome.
- The annual average temperature is 4.9 °C (8.8°F) warmer.
- Average monthly temperatures vary by 18.2 °C (32.8°F) less in Portland, Oregon. The continentality subtype is truly oceanic as opposed to truly continental.
- Total annual precipitation averages 202.5 mm (8 in) more which is equivalent to 202.5 l/m² (4.97 US gal/ft²) or 2,025,000 l/ha (216,486 US gal/ac) more. About 1 2/7 as much.
- There are 556 fewer hours of sunlight per year in Portland, Oregon. In whichever way circa 1h 31' less per day or about 7/9 as many.
- The altitude of the sun at midday is overall 0.7° lower in Portland, Oregon than in Minneapolis, Minnesota.
- Relative humidity levels are 10.4% higher.
- The mean dew point temperature is 6.8°C (12.2°F) higher.
