Consider a stable nocturnal boudary layer in a 12 hr night. The wind is blowing at 5 m/s and the surface is cooled with a kinematic heat flux of -0.02 K.m/s. The residual layer potential temperature is theta=25 degree centigrade.
a) what is the potential temperature profile at the end of the night?
b) plot the evolution of the height, h, of the stable boundary layer and the strength, delta thetas, as a function of time.
A successive approximation ADC has 4 bits and a reference voltage of 10 V. If the input voltage is 2.8 V, describe each step the ADC undergoes to determine the value of the 4 bits. What input voltage will be computed by the ADC?
