Document Summary

The object is deflected to the right of its anticipated course in the northern hemisphere and to the left in the southern hemisphere. The deflection occurs for any horizontal movement of objects with mass and has no effect at the equator. The observed deflection is caused by the observer"s moving frame of reference on the spinning earth. *the coriolis effect causes everything to move counter-clockwise in the southern hemisphere. Large circuit of air driven by uneven solar heating and the coriolis effect. 3 different circulation cells form in each hemisphere, for a total of 6; they are hadley cells (equator), ferrel cells (mid-latitude), and polar cells. A pair of cells located in the tropics, one on each side of the equator. The calm equatorial area where the surface winds of the 2 hadley cells converge. *this is an equatorial low, containing sultry air and variable breezes.

Use the result (9.73) of Problem 9.26 io do the following: A naval gun shoots a shell at colatitude theta in a direction that is a above the horizontal and due east, with muzzle speed v0. Ignoring the earth's rotation (and air resistance), find how long (l) the shell would be in the air and how far away (R) it would land. If v0 = 500 m/s and alpha = 20degree, what are t and R? A naval gunner sports an enemy ship due east at the range R of part (a) and, forgetting about the Coriolis effect, aims his gun exactly as in part (a). Find by how far north or south, and in which direction, the shell will miss the target, in terms of ohm, v0, alpha, theta, and g. (It will also miss in the east-west direction but this is perhaps less critical.) If the incident occurs at latitude 50degree north (theta = 40degree). What is this distance? What if the latitude is 50degree south? This problem is a serious issue in long-range gunnery: In a battle near the Falkland Islands in World War I, the British navy consistently missed German ships by many tens of yards because they apparently forgot that the Coriolis effect in the southern hemisphere is opposite to that in the north. In Section 9.8, we use a method of successive approximation to find the orbit of an object that is dropped from rest, correct to first order in the earth's angular velocity ohm. Show in the same way that if an object is thrown with initial velocity v0 from a point O on the earth's surface at colatitude theta, then to first order in ohm its orbit is (First solve the equation of motion(9.53) in zeroth) order. that is ignoring ohm entirely. Substitute your zeroth-order solution for and into the right side of equation (9.53) and integrate to give the next approximation. Assume that v0 is small enough that air resistance and that g is a constant throughout the flight) Use the result (9.73) of Problem 9.26 io do the following: A naval gun shoots a shell at colatitude theta in a direction that is a above the horizontal and due east, with muzzle speed v0.
