Final answer:
The mixing ratio and specific humidity are two different ways to express the amount of moisture in the air, but they are not significantly different numbers.
Step-by-step explanation:
The mixing ratio and specific humidity are two different ways to express the amount of moisture in the air, but they are not significantly different numbers. The mixing ratio is the mass of water vapor per mass of dry air, usually expressed in grams per kilogram. Specific humidity is the mass of water vapor per mass of moist air, usually expressed in grams per kilogram. While the specific values may differ slightly, the overall concept and units of measurement are similar.
