  Winds can be launched in tidal disruption event (TDE). It has been proposed
that the winds can interact with the cloud surrounding the black hole, produce
bow shocks, accelerate electrons, and produce radio emission. We restudy the
wind-cloud interaction model. We employ the properties of winds found by the
radiation hydrodynamic simulations of super-Eddington circularized accretion
flow in TDEs. We can calculate the peak radio emission frequency, the
luminosity at the peak frequency, and their time-evolution based on the TDEs
wind-cloud interaction model. We find that the model predicted peak radio
emission frequency, the luminosity at peak frequency, and their time evolution
can be well consistent with those in TDEs AT2019dsg and ASASSN-14li. This
indicates that in these two radio TDEs, the wind-cloud interaction mechanism
may be responsible for the radio emission.
