Comparison Among All‐Sky Simulations, FY‐3E MWTS‐3 and FY‐4A AGRI Observations of the First Typhoon Malakas in 2022
Abstract The newly launched early morning satellite Fengyun‐3E (FY‐3E) helps to form a three‐orbit constellation for better observing the first Typhoon Malakas in 2022. Together with MetOp‐B and NOAA‐20, global observations are made available 6 times daily from three temperature sounders of MWTS‐3,...

| description | Abstract The newly launched early morning satellite Fengyun‐3E (FY‐3E) helps to form a three‐orbit constellation for better observing the first Typhoon Malakas in 2022. Together with MetOp‐B and NOAA‐20, global observations are made available 6 times daily from three temperature sounders of MWTS‐3, AMSU‐A, and ATMS onboard FY‐3E, MetOp‐B, and NOAA‐20, respectively. Having channel frequencies much less than 200 GHz, brightness temperatures (TBs) at different sounding channels are linearly related to temperatures at different altitudes. This allows Malakas's warm cores to be retrieved from MWTS‐3, AMST‐A, and ATMS TB observations. The warm‐core maxima of Malakas at 250 hPa has a single‐peaked diurnal cycle, with its maximum and minimum peaking around midnight and noon, respectively. FY‐3E MWTS‐3 observations allowed the intensity and phase of the diurnal cycle better captured. The diurnal variations of warm core retrieved from all‐sky TB simulations of the ERA5 reanalysis and National Centers for Environmental Prediction (NCEP) Global Forecast System (GFS) analysis compared well with the three‐orbit constellation retrieval. All‐sky simulations of TB from the NCEP GFS analysis compared more favorably with FY‐4A AGRI TB observations than those from the ERA5 reanalysis. |
