Question
Consider a weather forecast model that currently generates an estimate of weather predictions at 6 hour increments up to 84 hours in advance. If we want to modify this weather model so that it can give us estimates of future weather conditions in ONE hour increments (increase in the temporal resolution), then which of the following would be required for the computing time to remain the same?
A The spatial resolution would need to be decreased.
B The spatial resolution would need to be increased.
C No changes to the spatial resolution would be needed.
Explanation / Answer
There there is no need to change the spatial resolution until we can have memory to save the large amount of database that we are going to get if we want data value at every hour as previously we are getting only one data value I every 6 hour but now we will get 6 value in 6 hours so we need to save more data as compared to previous case hence we don’t need to vary the spatial resolution, therefore option “C” is correct.
