How does radar detect thunderstorms? Doppler radar sends out electromagnetic wave fields that can be reflected back to the radar by things in the air like precipitation. The amount of energy that is reflected back can tell us how heavy the rain might be or tell us there is hail.
How is a thunderstorm detected? We can see thunderstorms with a variety of tools. Radars let us see where rain and hail are located in the storm. Doppler radars also let us see how the wind is blowing within and near the storm. Some features of thunderstorms, such as the anvil that spreads out at the top of the storm, can be seen from satellites.

Although small intestine tumors may not always be seen well on a CT, these scans are good at showing some of the problems that these tumors can cause (like an obstruction or perforation). CT scans can also help find areas of cancer spread.
How do you measure water level with a sensor?
With ultrasonic sensors, we can find the water depth calculation by finding the distance between the transceiver and the surface of the water. The sensor will transmit a short ultrasonic pulse, and we can measure the travel time of that pulse (the echo) to the liquid and back.
Can steam tell if a game is pirated?
Steam actively promotes an anti-piracy culture and by offering games at such low prices, you simply don’t have to worry about pirating games anymore! So, in a nutshell, no, Steam does not detect that you are pirating a game!

Do mini fridges ever leak?
The mini-fridge, with its propensity for building up frost, can also leak a lot of water if you’re not careful. Condensation can build up, especially if the fridge is full since the air will not flow through the fridge as effectively and condensation will build up in pockets throughout the fridge.
How do you check for cracks in walls?
To determine how serious a wall crack might be, it’s best to examine the shape of the crack and the direction it runs on the wall. If the crack is vertical and starts near the apex where the wall and ceiling meet, it might be a sign that it was created when the foundation settled after construction.
What type of pulse is seen in aortic regurgitation?

Where can magnetic anomalies be found?
As new crust is produced in Earth’s mid-oceanic ridges and the seafloor spreads, they move in recognizable, stripe-like patterns. You can also spot magnetic anomalies—places with unusually high amounts of magnetism—on the map. One such anomaly is in the Central African Republic.
How is GFP expression detected?
Flow cytometry and fluorescent microscopy are two conventional tools to detect the GFP signal; flow cytometry is an effective and sensitive technique to quantitatively analyze fluorescent intensity, while fluorescent microscopy can visualize the subcellular location and expression of GFP.
