convert array to scalar for subtraction?

Dear NCL,

I would like to subtract one array from another: x-y

x has dimensions [time | 199] x [lat | 64] x [lon | 128]
y has dimensions [time | 1] x [lat | 64] x [lon | 128]

fatal:Minus: Dimension size, for dimension number 0, of operands does
not match, can't continue

I understand why I get the error. How can I convert the time
dimension of y to a scalar so that I can subtract it from each time
dimension of x? Or is there a better way?

Thank you for your help.
