In this paper, we systematically study weighted jump and variational inequalities for rough operators. More precisely, we show some weighted jump and variational inequalities for the families T:={T ε} ε> 0 of truncated singular integrals and M Ω:={M Ω, t} t> 0 of averaging operators with rough kernels, which are defined respectively by T ε f (x)=∫| y|> ε Ω (y′)| y| n f (x− y) d y and M Ω, t f (x)= 1 t n∫| y|< t Ω (y′) f (x− y) d y, where the kernel Ω belongs to L q (S n− 1) for q> 1.
