more pressure ='s higher temp
less pressure ='s lower temp

The formation of low pressure and high pressure systems all over the world is due to the differential heating of the earth's surface (and the atmosphere) by the solar radiation.The gas law states that PV=RT.Here the pressure increases in direct proportion to the temperature provided the volume is constant.But ,in the atmosphere volume cannot be kept constant.If air is heated in the atmosphere ,it expands and occupies more volume.
So, in atmosphere,the reverse thing happens.If the land is heated more,low pressure is created there.Sea-breeze, in coastal areas is an example.The land is heated more than the adjacent sea surface and a pressure gradient is created with low pressure over land and high pressure over sea.Wind starts blowing as sea-breeze from the sea towards land.
Further ,from the charts of barograph and Thermograph where continuous (24 hours) values of pressure and temperature are recorded respectively,(which give the diurnal variation of pressure and temperature for a day),it can be seen that whenever maximum temperature is recorded,the pressure values will be minimum for the corresponding time.
So it can be clearly said,that more temperature means less pressure.

crap I will make this simple as I can. I was in college 17 years ago.
High air pressure is a stable. It moves all over the place. its more dense the the air moving around it. Its like a brick wall. Air pressure is what creates wind. But the air blowing is less dense. Meaning it has to go around the high air pressure as the low air pressure is sucking the wind in.
How does it affect temp? Simple. I will use Utah for an example. Get a map or just imagine. Lets say the high airpressure is in Idaho, just north of utah. The wind coming from canada is blocked. It goes around the high pressure. The wind we get is from mexico and arizona. Makes us warm.
Lets say the high pressure is in arizona, south of utah. Then we have the winds coming from canada and alaska. It makes us cold.
Air pressure determines how the Jet Streams run. Where the air pressure is at determines if you are cold or hot.
The air moves around it. Depends on which side of the air pressure you are at if its warm or cold.
Low air pressure can suck warm or cold air in depending on the high pressure. Low pressure doesnt mean cold. It could mean freaking hot.

Yes, watch the equation for the perfect gases: To * Po = T1 *P1 Experiment: have a metal container with a known volume and attach firmly to it a Manometer and a bimetal Thermometer, fill it with some gas, let us say simple AIR, Then start heating gently, you will see not only the temperature start raising, but also the pressure, volume is neglected because it does not change. The beautiful of this experiment is that always your values in the instruments will be in equilibrium according to the above equation.

when you increase the temperature of gasses then the air pressure increases to. For example, when you have a ballon and you heat it up the air will fell more pressure and that will cause the ballon to blow up. When you heatcells up they move faster. Common this is 7th grade level science wow

they're not really related...
in response to previous answer, high air pressure does not necessarily mean high air temperature.

low air pressure=precipitation=lower temp.
high press in summer=less clouds=more sun=more heat
high press in winter=less clouds to hold heat in=colder temp
