john who lives at 35 degrees north and 120 degrees west regularly calls Geroge his business partnet at 2pm (John's local time) every day during July last year. George regularly recevied the calls at 10 pm ( his local time). throughout the month, George reported that the maximum diurnal temperature in his station (location) was never below 75 degrees F and the minimum dirunal temperature never below 70 degrees F.

i) in what latitudinal zone was george located?
ii) what was the mean diurnal temperature for july at georges location?
iii) what was the diurnal temperature range for july at georges location?
iv) in what koppens climatic class would you put johns location?

Steve answered at least one of your questions yesterday.

The other two sites should help you.

omg thanks i needed help on that one too! still working on the other parts

i) To determine the latitudinal zone of George's location, we need to find the latitude which corresponds to 10 pm being the local time for sunset in July. This information can be obtained by using an online tool or software that provides sunrise and sunset times for different locations and dates. By entering George's location and the date range for July last year, we can find the latitude at which the sunset occurs around 10 pm local time.

ii) To calculate the mean diurnal temperature for July at George's location, we need daily temperature data for the entire month. This data could be obtained from meteorological records, weather websites, or climate databases. By summing up the daily temperatures and dividing by the number of days in July, we can find the mean diurnal temperature.

iii) The diurnal temperature range for July at George's location can be calculated by finding the difference between the maximum and minimum daily temperatures. From the information given, we know that the maximum diurnal temperature was never below 75 degrees F and the minimum diurnal temperature never below 70 degrees F. Therefore, the diurnal temperature range can be established as the difference between these two values.

iv) To determine the Köppen climate classification for John's location, we need more information such as the average annual temperature and precipitation data for his location. The Köppen climate classification system takes into account temperature, precipitation, and other factors to categorize climates. Without additional information, it is not possible to accurately determine the Köppen climate class for John's location.
