Normal air pressure is 985 millibars. What is the difference between the air pressure in the eye of the storm and normal air pressure?

"Normal" air pressure varies a fair bit - the pressure used as "1 atmosphere" in calculations is ~101.3 kPa - this is from the "Standard Temperature and Pressure"
1 bar is 100 kPa, and 1000 millibars. Of course, I don't know where you are, so I can't account for pressure differences based on elevation or prevailing weather patterns. (Not being a meteorologist, I cannot even do the latter.) So your source for "normal" air pressure being 985 millibars is somewhat questionable, though still reasonable. (If you're talking about in-storm-system pressure, it becomes a lot more reasonable an assumption, though I'd double check it regardless.)
Now, in the eye of a tropical storm, Wikipedia's article on tropical storm eyes indicates the pressure may be as much as 15% lower than the air pressure in the rest of the storm (or a minimum reasonable pressure of 85% of the storm pressure. Their citation for this statement is "^ a bc Landsea, Chris and Sim Aberson. (August 13, 2004). "What is the "eye"?".

Comparison between normal temperature pressure and standard temperature pressure?
there is no difference
What is the air density in a hurricane?
Air pressure inside a hurricane is low typically less than 995 millibars (normal sea level pressure is 1013 millibars). Stronger hurricanes generally have a lower central pressure.
The difference between the systolic and diastolic pressure is called the?
The first number recorded in a blood pressure measurement is the systolic pressure and represents the peak pressure generated by cardiac contraction. The second number is the diastolic pressure and represents the intravascular pressure during relaxation of the heart while it is filling. The difference between these two measurements is called the pulse pressure. So, for a normal BP reading of 120/80, there would be a normal pulse pressure of 40.
What is Normal air pressure on earth?
Earth doesn't have one continuous, constant atmospheric pressure, it varies both spatialy and temporally. Assuming you're talking about the atmospheric pressure at the Earth's surface, the "standard" atmospheric pressure is 1000 millibars (mb), however pressures can range anywhere from ~875 mb (in intense low pressure areas such as the center of tropical cyclones) to ~1080mb.
Do hurricanes have lower air pressure than tornadoes?
That is a difficult question to answer. It is true that the lowest pressure recorded in a tornado (688 millibars) was much lower than the record low pressure for a tropical cyclone (870). But very few measurements have been taken from inside a tornado, so it is unknown what pressures would be normal.
Is 1034 millibars high pressure?
Yes, 1034 millibars in barometric pressure is high. Normal pressure is 1013 millibars.
What is normal atmosphere measured in?
Atmospheric pressure is measured by a barometer and expressed in millibars. Normal atmospheric pressure at sea level is 1013 millibars.
What is the air pressure inside a hurricane?
Air pressure inside a hurricane is low typically less than 995 millibars (normal sea level pressure is 1013 millibars). Stronger hurricanes generally have a lower central pressure.
Comparison between normal temperature pressure and standard temperature pressure?
there is no difference
What is the difference between normal pressure gauge and differential pressure gauge?
A pressure gauge indicates actual pressure and a differential pressure gauge indicates the difference in pressure.
What is the correlation between pressure level and millibars?
1 pascal is 0.01 millibars and 1 millibar is 100 pascals. Mathematically pressure is:p = F / Awhere:p is the pressure,F is the normal force,A is the area. Pressure level Lp is a logarithmic measure of the rms pressure relative to a reference value. It is measured in decibel (dB). Pressure level in dB: Lp = 20 log (p / pref) where pref is the reference pressure and p is the rms pressure being measured. Look for the right reference pressure.
What is the air density in a hurricane?
Air pressure inside a hurricane is low typically less than 995 millibars (normal sea level pressure is 1013 millibars). Stronger hurricanes generally have a lower central pressure.
What is the difference between NTP and STP?
Yes, there is a little difference between NTP (Normal Temperature-Pressure) & STP (Standard Temperature-Pressure). There are detailed scientific and encyclopedic reasons behind it.
The difference between the systolic and diastolic pressure is called the?
The first number recorded in a blood pressure measurement is the systolic pressure and represents the peak pressure generated by cardiac contraction. The second number is the diastolic pressure and represents the intravascular pressure during relaxation of the heart while it is filling. The difference between these two measurements is called the pulse pressure. So, for a normal BP reading of 120/80, there would be a normal pulse pressure of 40.
What is the pressure at the center of a hurricane?
The central pressure of the hurricane measures how strong the hurricane is. The lower the pressure is in the center of the hurricane, the higher the winds. If the pressure is very low, it is a very strong hurricane.
How much do cooking times change when using a pressure cooker instead of a normal pot?
Between cooking with a normal pot and a pressure cooker the difference in terms of time is not much. The pressure cooker can be used depending on the type of food that is cooked.
Air pressure is measured in which of the following units?
Atmospheric pressure is measured by a barometer and expressed in millibars. Normal atmospheric pressure at sea level is 1,013 millibars. Pressure is also measured in pascals, which is the pressure of 1 newton over 1 square meter. (A newton is the amount of force needed to accelerate 1 kilogram by 1 meter per second per second. 'atmosphere' itself is a unit , abbreviated as atm. 1atm=1.013 x 105. In the English system, pressure is measured in pounds per square inch. A pound per square inch is equal to about 6,890 pascal.
