colorbar label along y-axis instead of x-axis

Hello! I would like the colorbar label to appear directly underneath the colorbar (right underneath the "220" in the figure below), horizontal along the x axis. However, when I specify this as follows, it aligns the label along the y axis.

Here is the relevant code:

contourf(lon,lat,tmp2, 25, 'LineStyle','none');

hold on

colormap('turbo')

set(gca,'fontsize',14);

ylabel('Latitude (\circ)')

xlabel('Longitude (\circ)')

h = colorbar;

xlabel(h,'(K)');

hold off

------

can someone help me change the orientation of that '(K)', and show me how to adjust my code in general so I can make this adjustments in other plots as well? Thanks.

% generate random data:
lon = 0:359;
lat = -90:90;
tmp2 = 217+96*rand(numel(lat),numel(lon));

contourf(lon,lat,tmp2, 25, 'LineStyle','none');
colormap('turbo')
set(gca,'fontsize',14);
ylabel('Latitude (\circ)')
xlabel('Longitude (\circ)')
h = colorbar;
xlabel(h,'(K)');

h.Label.Units = 'normalized';
h.Label.Position = [2 0]; % more-or-less centered under the colorbar tick labels
h.Label.Rotation = 0;

Alternatively, you can use

h.Label.Position = [0.5 0]; % centered under the colorbar itself

to center the colorbar label under the colorbar itself, or adjust the first element (or both elements) of that Position as desired.

Position is [x,y] and Units are normalized to the colorbar itself, so [0 0] would place the label at the lower-left of the colorbar, [1 1] would place it at the upper-right, [0 1] would be upper-left, and [1 0] would be lower-right. The label has VerticalAlignment 'top' and Horizontalignment 'center', so the Position is where the top center of the label will be located.

This provided exactly what was needed. Thank you so much!!
