Neptune's weather is characterised by extremely dynamic storm systems, with winds reaching speeds of almost 600 m/s (2,200 km/h; 1,300 mph)nearly reaching supersonic flow. More typically, by tracking the motion of persistent clouds, wind speeds have been shown to vary from 20 m/s in the easterly direction to 325 m/s westward. At the cloud tops, the prevailing winds range in speed from 400 m/s along the equator to 250 m/s at the poles. Most of the winds on Neptune move in a direction opposite the planet's rotation. The general pattern of winds showed prograde rotation at high latitudes vs. retrograde rotation at lower latitudes. The difference in flow direction is thought to be a "skin effect" and not due to any deeper atmospheric processes. At 70 S latitude, a high-speed jet travels at a speed of 300 m/s.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is the effect called that describes the flow direction on Neptune?
Ah, so.. skin effect

Melbourne has a temperate oceanic climate (Koppen climate classification Cfb) and is well known for its changeable weather conditions. This is mainly due to Melbourne's location situated on the boundary of the very hot inland areas and the cool southern ocean. This temperature differential is most pronounced in the spring and summer months and can cause very strong cold fronts to form. These cold fronts can be responsible for all sorts of severe weather from gales to severe thunderstorms and hail, large temperature drops, and heavy rain.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Is Melbourne known for changeable or steady weather patterns?
Ah, so.. changeable

With too low a bit rate, compression artifacts (i.e., sounds that were not present in the original recording) may be audible in the reproduction. Some audio is hard to compress because of its randomness and sharp attacks. When this type of audio is compressed, artifacts such as ringing or pre-echo are usually heard. A sample of applause compressed with a relatively low bit rate provides a good example of compression artifacts.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Other than pre - echo, what is another example of what can happen when audio is compressed?
Ah, so..
ringing
