The normal boiling point (also called the atmospheric boiling point or the atmospheric pressure boiling point) of a liquid is the special case in which the vapor pressure of the liquid equals the defined atmospheric pressure at sea level, atmosphere
Yes. In general, higher altitudes mean lower atmospheric pressure. Lower atmospheric pressure means lower boiling points.
In order for a storm to form there's one thing that's an absolute must-have for it, that would be low atmospheric pressure. Generally the lower the pressure, the more intense a storm can get. The data we can collect ahead of time would be atmospheric pressure data. Atmospheric pressure can be measured in mbs or inHG.
It results in a lower atmospheric pressure.
Water boils when its internal pressure reaches that of the atmospheric pressure. Therefor, if one lowers the atmospheric pressure, the water would boil at a lower temperature (in fact, one can make water boil at room temperature by dramatically lowering the atmospheric pressure).
in Lower pressure water does not have to get as hot to boil
The boiling point of any liquid is the temperature at which its vapor pressure becomes equal to the atmospheric pressure. So if the atmospheric pressure is lower, it will take a lower temperature to make the vapor pressure equal to that of atmospheric pressure. At hill-stations, the air is generally thinner due to the altitude and the atmospheric pressure is also lower. Here, it requires less than 100oC temperature to reach the point where the vapor pressure of water reaches that of air. So, water boils below 100oC at hill stations.

The atmospheric pressure is lower. When you are boiling the water, the water's vapour saturation pressure is able to match the atmospheric pressure faster therefore it boils faster and at a lower temperature.
lower atmospheric pressure
It results in a lower atmospheric pressure.
The higher the pressure, the higher the boiling point. Boiling occurs when the atmospheric pressure equals the vapor pressure. So, at higher altitudes where the atmospheric pressure is lower, the vapor pressure is also lower which in turn creates a lower boiling point which causes foods to have to cook longer.
On a windy day atmospheric pressure decreases because the higher the wind velocity, the lower the air pressure, or atmospheric pressure. This is how chimneys work, the air that moves above the chimney causes low air pressure because of the high wind velocity compared the velocity of the air inside a house. The air inside the house goes towards the low air pressure and takes the smoke with it.
The boiling of any liquid is tied in to the atmospheric pressure, in an open system. Every liquid has it's own vapor pressure, that is the balance between the vapor and liquid phase. When atmospheric pressure decreases, the vapor pressure increases since now there is greater space for the molecules of the liquid to come into vapor phase. At higher altitudes, the atmospheric pressure is lesser, that is, the air is thinner. Thus the liquid can attain higher vapor pressure faster and boil at a lower temperature.
