Alignments, crossings and inversions of signed permutations are realized in the corresponding permutation tableaux of type B, and the cycles of signed permutations are understood in the corresponding bare tableaux of type B. We find the relation between the number of alignments, crossings and other statistics of signed permutations, and also characterize the covering relation in weak Bruhat order on Coxeter system of type B in terms of permutation tableaux of type B.
