In 1 atmosphere is how many millibars are there

(Round to the nearest whole millibar)

what is 1013 millibars

800

what moves air masses in the atmosphere

what are convection currents and trade winds

800

What is the Coriolis Effect.

The effect causes objects in the atmosphere curve instead of going straight.

If a dry-bulb parcel is 26℃ and the relative humidity is 39% what is the wet-bulb temperature and dew point 

wet-bulb is 17℃ and the dew point is 11℃

What is the relationship between Dew Point and Relative Humidity

If the Relative Humidity is higher the difference in Dew Point and the temperature are closer.

An air mass created in Idaho (cP) goes over the Great Lakes does the air mass change and if so what is the new air mass

It changes to a mP airmass because of the absorption of water over the great lakes.
