Narrative:

During takeoff from 27L in phl; winds reported prior to takeoff 320/9. The hour old ATIS reported gust earlier 360@16/G30. With the more current report we felt comfortable we were within limits and that the wind had died down. Having used our resources; we applied the windshear guidance procedures and elected a max thrust takeoff; longest runway with an adjusted vr of 140. On takeoff roll; we experienced some sort of massive gust or wing tip vortices from the previous airbus 321 which pushed the nose about 20-30 [degrees] left. Having my hands in a grasp position; I accidentally removed toga power momentarily due to the lateral jolt. Passed 80 knots; I elected to continue after first officer regained immediate directional control. I quickly reapplied toga and called rotate at preplanned adjusted vr. We rotated halfway down 27L and the remainder of the flight was uneventful. Due to the lateral movement; I called the purser to ensure everyone was okay; she reaffirmed everyone was okay. I think even with a highly experienced first officer; I'll elect to conduct the takeoff next time when there is any doubt of a potential direct crosswind scenario in addition to wind shear precautions being used. I feel I need to adjust my hands as not to grasp the thrust levers on takeoff to prevent an inadvertent thrust reduction in the future. This was an eye opener for me and I learned a lot from the experience.

Title: ERJ-190 Captain reported the nose swung 20 to 30 degrees left on the takeoff roll in response to a wind gust or wake from the previous takeoff.

Having my hands in a grasp position; I accidentally removed TOGA power momentarily due to the lateral jolt. Passed 80 knots; I elected to continue after FO regained immediate directional control. I quickly reapplied TOGA and called rotate at preplanned adjusted Vr. We rotated halfway down 27L and the remainder of the flight was uneventful.
