PISTON 2018 saw enhanced seasonal vorticity anomaly over western North Pacific that supports easterly wave propagation. Invest98 was an interesting cast that the disturbance was intensifying after spinning up from Super Typhoon Jebi's rainband. Invest98 produced more than 200mm rain over our shipborne Sea-Pol radar. Convective systems ranging from isolated to linearly organized MCS. With this case study, we aim to learn more about the multi-scale TC genesis problem, bridging the gap between large-scale wave mode and meso-scale convection.
