Creating an Animation of the World from Discrete Blocks

Consider a map of the world. This map has been separated into 108 blocks, and I have been given data on each block. I thought if I could create an animation for each block, I could then merge all 108 animations to form an animation of the world. The following script appears to create an animation for a single block.

ncfile2 = 'mhw_severity.pc90.0to30.30to50.1981.2019.nc' ; % nc file

lat=ncread(ncfile2,'lat');
lon=ncread(ncfile2,'lon');
ssta=ncread(ncfile2,'ssta');

for i=1:1000
    imagesc(lat,lon,ssta(:,:,i))
    i
    pause(0.001)
end

Is there a more efficient way that this can be achieved?
