Wind belts: symmetric case, and then land effects

Length of the day varies by milliseconds due to climate Angular momentum Change in length of day (10-3s) time Length of the day varies by milliseconds due to climate

Wind as a function of latitude and height Dec/Jan/Feb Jun/Jul/Aug Note the stronger jet in the winter hemisphere

Temperature as a function of latitude and height Dec/Jan/Feb Jun/Jul/Aug Note the warmer summer hemisphere (duh)

Northern hemisphere winter (Dec Jan Feb) – Sea level pressure Icelandic Low Aleutian Low Siberian High

Northern hemisphere winter (Dec Jan Feb) – Surface wind Note the approximate geostrophic balance (c.f. pattern of surf. pressure)

Northern hemisphere Winter circulation – pressure at 3km What is the Geostrophic balance here?

Northern hemisphere Winter circulation – pressure at 5.5km What is the Geostrophic balance here?

Northern hemisphere Winter circulation – pressure at 9.0km What is the Geostrophic balance here?

Northern hemisphere - temperature difference from zonal average in lower troposphere. (0 to 5 km)

Heat flux from surface to atmosphere (Winter) Wm-2 Cooling over land, heating over ocean (up to 4000W/m2 in a big storm)

Northern hemisphere winter (Dec Jan Feb) – Precipitation rate Precipitation organized into storm tracks in Atlantic and Pacific basins

Storm tracks in the atmosphere Density of tracks of storms in DJF, northern hemisphere

Southern hemisphere winter (Jun Jul Aug) – Sea level pressure Pattern is much more zonal (east west) than Northern hemisphere

Southern hemisphere winter (Jun Jul Aug) – Surface wind Note the approximate geostrophic balance (in southern hemisphere!)

Southern hemisphere winter circulation- pressure at 5.5km What is the Geostrophic balance here?

Southern hemisphere: heat flux from surface to atmosphere (Winter) Wm-2

Southern hemisphere winter precipitation (ish!) What about the pattern here?

Storm tracks in the atmosphere Density of tracks of storms in JJS, southern hemisphere Distributions of storm are much more uniform
