    "abstract": "We investigated numerically the relation between a roller and the pressure\ndistribution to clarify the dynamics of the roller in circular hydraulic jumps.\nWe found that a roller which characterizes a type II jump is associated with\ntwo high pressure regions after the jump, while a type I jump (without the\nroller) is associated with only one high pressure region. Our numerical results\nshow that building up an appropriate pressure field is essential for a roller.",
