The technology most commonly used by weather services to track the movement and intensity of typhoons is Doppler radar.

Step 1: Understand the question - The question is asking about the specific technology used by weather services to monitor typhoons.

Step 2: Eliminate incorrect options - Seismographs are used to measure earthquakes, not weather phenomena. Barometers measure atmospheric pressure, which can be used in weather prediction, but not specifically for tracking typhoons. Flood gauges measure the level of water in a body of water or flow rate of a water source, which is not directly related to tracking typhoons.

Step 3: Choose the correct option - Doppler radar is used to produce velocity data about objects at a distance. It does this by bouncing a microwave signal off a desired target and analyzing how the object's motion has altered the frequency of the returned signal. This can be used to measure the velocity of rain droplets in a typhoon, which can provide information about its direction and intensity. Therefore, Doppler radar is the correct answer.
