The first cold weather alerts of the season, including a Freeze Warning and Frost Advisory, will be in effect for parts of ...

Doppler radars derive their name due to the method with which they measure the velocities. The Doppler Effect was proposed by Christian Andreas Doppler in 1842, and states that the frequency of a wave ...

If we regard the subject classically, the result to be expected is obvious: there should be a Doppler broadening of the incident spectral line, varying with the angle of observation, and ...

A flood advisory is in effect for Guam until 4 p.m. Sunday, according to the National Weather Service. Doppler radar ...

You might notice a gap between the advisory and the warning. An area of clouds coming off Lake Michigan will keep the frost and freeze to a minimum from Lafayette to Kokomo to Indianapolis. A mix of ...

The idea has links to the doppler effect, which can make light appear red or blue shifted depending on how the emitting object is moving relative to us, as well as the rotational doppler effect.

The brains of kids who are teaching peers go into overdrive—boosting retention and understanding. Here’s how to leverage this ...

In preliminary Doppler sonographic studies of healthy young ... These changes seem to be due to a vasodilator effect of sildenafil on female genital tissues. Recently, NO synthase isoforms have ...

The Doppler effect is a change in wavelength (frequency) of sound resulting from motion of a source, receiver or reflector. As the US transducer is a stationary source and receiver, the Doppler effect ...

Some 40 years earlier in 1842 the Austrian physicist Christian Doppler had discovered what is now called the Doppler effect. This is the theory that sound waves will change in pitch when there is a ...

The coldest air since April is diving south toward Indiana with the chance for our first frost and freeze arriving midweek.
