[Wrf-users] Questions regarding how simulation domain settng up

[曹智选]

Hello,
I am runing WRF with nested domain to get higher resolution meteorological
data for a specific region. So the longutide range and latitude range of
this specific domain is known.

How to determine i_start and j_start for the nested domain so that these
"finer-resolution domain" covers the region of interest.

To be more specific, I am looking for detailed documentaion that can tell
me the map between real world (Earth's surface and atmosphere above) to the
vitual world (The simulation domain.).

Chapter 3 of user manual gives a little information. As for projection
"Polar Stereographic" and "Lambert ",  the projected earth surface can not
fill up the rectangular box. There are some "empty areas".  So what will be
the simulation domain looks like. Is it a regular box?

In WRF simulation, should the nodes carries meteorological data concide
with nodes of coarse domain?

Thank you!
